+---------------------------

+============================
+
+As documented in the mail below, if you are using a system without any
+version of awk installed, you will have bootstrapping problems (i.e., running
+configure).  The solution is to install mawk or Brian Kernighan's awk
+first.

+Message-ID: <87r514faw9.fsf@latte.josefsson.org>
+Subject: [bug-gawk] building gawk requires an awk?
+
+Hello,
+
+I was not able to build gawk 4.0.0 on a GNU/Hurd machine that didn't
+have any awk, the ./configure script failed at the end:
+
+config.status: creating Makefile
+./config.status: line 1169: awk: command not found
+config.status: error: could not create Makefile
+
+Is this a known bootstrapping issue?  Same happened for 3.1.8.  I looked
+in README but didn't find anything obvious.
+
+Btw, building 'mawk' first and then gawk 4.0.0 works.  Running self
+checks didn't work because there is no 'cmp' on the system either...
+

-       tokens because there are none.
-     - The only way there can be no lookahead present (in yychar) is if
-       this state is a consistent state with a default action.  Thus,
-       detecting the absence of a lookahead is sufficient to determine
-       that there is no unexpected or expected token to report.  In that
-       case, just report a simple "syntax error".
-     - Don't assume there isn't a lookahead just because this state is a

-       previous inconsistent state, consistent state with a non-default
-       action, or user semantic action that manipulated yychar.
-     - Of course, the expected token list depends on states to have
-       correct lookahead information, and it depends on the parser not
-       to perform extra reductions after fetching a lookahead from the
-       scanner and before detecting a syntax error.  Thus, state merging
-       (from LALR or IELR) and default reductions corrupt the expected
-       token list.  However, the list is correct for canonical LR with

+
+8.1.6 Using Predefined Array Scanning Orders
+--------------------------------------------
+
+By default, when a `for' loop traverses an array, the order is
+undefined, meaning that the `awk' implementation determines the order
+in which the array is traversed.  This order is usually based on the
+internal implementation of arrays and will vary from one version of
+`awk' to the next.
+
+   Often, though, you may wish to do something simple, such as
+"traverse the array by comparing the indices in ascending order," or
+"traverse the array by on comparing the values in descending order."
+`gawk' provides two mechanisms which give you this control.
+
+   * Set `PROCINFO["sorted_in"]' to one of a set of predefined values.
+     We describe this now.
+
+   * Set `PROCINFO["sorted_in"]' to the name of a user-defined function
+     to be used for comparison of array elements. This advanced feature
+     is described later, in *note Array Sorting::.
+
+   The following special values for `PROCINFO["sorted_in"]' are
+available:
+
+`"@unsorted"'
+     Array elements are processed in arbitrary order, which is the
+     default `awk' behavior.
+
+`"@ind_str_asc"'
+     Order by indices compared as strings; this is the most basic sort.
+     (Internally, array indices are always strings, so with `a[2*5] = 1'
+     the index is `"10"' rather than numeric 10.)
+
+`"@ind_num_asc"'
+     Order by indices but force them to be treated as numbers in the
+     process.  Any index with a non-numeric value will end up
+     positioned as if it were zero.
+
+`"@val_type_asc"'
+     Order by element values rather than indices.  Ordering is by the
+     type assigned to the element (*note Typing and Comparison::).  All
+     numeric values come before all string values, which in turn come
+     before all subarrays.  (Subarrays have not been described yet;
+     *note Arrays of Arrays::).
+
+`"@val_str_asc"'
+     Order by element values rather than by indices.  Scalar values are
+     compared as strings.  Subarrays, if present, come out last.
+
+`"@val_num_asc"'
+     Order by element values rather than by indices.  Scalar values are
+     compared as numbers.  Subarrays, if present, come out last.  When
+     numeric values are equal, the string values are used to provide an
+     ordering: this guarantees consistent results across different
+     versions of the C `qsort()' function,(1) which `gawk' uses
+     internally to perform the sorting.
+
+`"@ind_str_desc"'
+     Reverse order from the most basic sort.
+
+`"@ind_num_desc"'
+     Numeric indices ordered from high to low.
+
+`"@val_type_desc"'
+     Element values, based on type, in descending order.
+
+`"@val_str_desc"'
+     Element values, treated as strings, ordered from high to low.
+     Subarrays, if present, come out first.
+
+`"@val_num_desc"'
+     Element values, treated as numbers, ordered from high to low.
+     Subarrays, if present, come out first.
+
+   The array traversal order is determined before the `for' loop starts
+to run. Changing `PROCINFO["sorted_in"]' in the loop body will not
+affect the loop.
+
+   For example:
+
+     $ gawk 'BEGIN {
+     >    a[4] = 4
+     >    a[3] = 3
+     >    for (i in a)
+     >        print i, a[i]
+     > }'
+     -| 4 4
+     -| 3 3
+     $ gawk 'BEGIN {
+     >    PROCINFO["sorted_in"] = "@ind_str_asc"
+     >    a[4] = 4
+     >    a[3] = 3
+     >    for (i in a)
+     >        print i, a[i]
+     > }'
+     -| 3 3
+     -| 4 4
+
+   When sorting an array by element values, if a value happens to be a
+subarray then it is considered to be greater than any string or numeric
+value, regardless of what the subarray itself contains, and all
+subarrays are treated as being equal to each other.  Their order
+relative to each other is determined by their index strings.
+
+   Here are some additional things to bear in mind about sorted array
+traversal.
+
+   * The value of `PROCINFO["sorted_in"]' is global. That is, it affects
+     all array traversal `for' loops.  If you need to change it within
+     your own code, you should see if it's defined and save and restore
+     the value:
+
+          ...
+          if ("sorted_in" in PROCINFO) {
+              save_sorted = PROCINFO["sorted_in"]
+              PROCINFO["sorted_in"] = "@val_str_desc" # or whatever
+          }
+          ...
+          if (save_sorted)
+              PROCINFO["sorted_in"] = save_sorted
+
+   * As mentioned, the default array traversal order is represented by
+     `"@unsorted"'.  You can also get the default behavior by assigning
+     the null string to `PROCINFO["sorted_in"]' or by just deleting the
+     `"sorted_in"' element from the `PROCINFO' array with the `delete'
+     statement.  (The `delete' statement hasn't been described yet;
+     *note Delete::.)
 
    In addition, `gawk' provides built-in functions for sorting arrays;
-see *Note Array Sorting Functions::.
+see *note Array Sorting Functions::.
+
+   ---------- Footnotes ----------
+
+   (1) When two elements compare as equal, the C `qsort()' function
+does not guarantee that they will maintain their original relative
+order after sorting.  Using the string value to provide a unique
+ordering when the numeric values are equal ensures that `gawk' behaves
+consistently across different environments.

-until @ref{Controlling Array Traversal}.
+@node Controlling Scanning
+@subsection Using Predefined Array Scanning Orders
+
+By default, when a @code{for} loop traverses an array, the order
+is undefined, meaning that the @command{awk} implementation
+determines the order in which the array is traversed.
+This order is usually based on the internal implementation of arrays
+and will vary from one version of @command{awk} to the next.
+
+Often, though, you may wish to do something simple, such as
+``traverse the array by comparing the indices in ascending order,''
+or ``traverse the array by on comparing the values in descending order.''
+@command{gawk} provides two mechanisms which give you this control.
+
+@itemize @bullet
+@item
+Set @code{PROCINFO["sorted_in"]} to one of a set of predefined values.
+We describe this now.
+
+@item
+Set @code{PROCINFO["sorted_in"]} to the name of a user-defined function
+to be used for comparison of array elements. This advanced feature
+is described later, in @ref{Array Sorting}.
+@end itemize
+
+The following special values for @code{PROCINFO["sorted_in"]} are available:
+
+@table @code
+@item "@@unsorted"
+Array elements are processed in arbitrary order, which is the default
+@command{awk} behavior.
+
+@item "@@ind_str_asc"
+Order by indices compared as strings; this is the most basic sort.
+(Internally, array indices are always strings, so with @samp{a[2*5] = 1}
+the index is @code{"10"} rather than numeric 10.)
+
+@item "@@ind_num_asc"
+Order by indices but force them to be treated as numbers in the process.
+Any index with a non-numeric value will end up positioned as if it were zero. 
+
+@item "@@val_type_asc"
+Order by element values rather than indices.
+Ordering is by the type assigned to the element
+(@pxref{Typing and Comparison}).
+All numeric values come before all string values,
+which in turn come before all subarrays.
+(Subarrays have not been described yet;
+@pxref{Arrays of Arrays}).
+
+@item "@@val_str_asc"
+Order by element values rather than by indices.  Scalar values are 
+compared as strings.  Subarrays, if present, come out last.
+
+@item "@@val_num_asc"
+Order by element values rather than by indices.  Scalar values are 
+compared as numbers.  Subarrays, if present, come out last.
+When numeric values are equal, the string values are used to provide
+an ordering: this guarantees consistent results across different
+versions of the C @code{qsort()} function,@footnote{When two elements
+compare as equal, the C @code{qsort()} function does not guarantee
+that they will maintain their original relative order after sorting.
+Using the string value to provide a unique ordering when the numeric
+values are equal ensures that @command{gawk} behaves consistently
+across different environments.} which @command{gawk} uses internally
+to perform the sorting.
+
+@item "@@ind_str_desc"
+Reverse order from the most basic sort.
+
+@item "@@ind_num_desc"
+Numeric indices ordered from high to low.
+
+@item "@@val_type_desc"
+Element values, based on type, in descending order.
+
+@item "@@val_str_desc"
+Element values, treated as strings, ordered from high to low.
+Subarrays, if present, come out first.
+
+@item "@@val_num_desc"
+Element values, treated as numbers, ordered from high to low.
+Subarrays, if present, come out first.
+@end table
+
+The array traversal order is determined before the @code{for} loop
+starts to run. Changing @code{PROCINFO["sorted_in"]} in the loop body
+will not affect the loop.
+
+For example:
+
+@example
+$ @kbd{gawk 'BEGIN @{}
+> @kbd{   a[4] = 4}
+> @kbd{   a[3] = 3}
+> @kbd{   for (i in a)}
+> @kbd{       print i, a[i]}
+> @kbd{@}'}
+@print{} 4 4
+@print{} 3 3
+$ @kbd{gawk 'BEGIN @{}
+> @kbd{   PROCINFO["sorted_in"] = "@@ind_str_asc"}
+> @kbd{   a[4] = 4}
+> @kbd{   a[3] = 3}
+> @kbd{   for (i in a)}
+> @kbd{       print i, a[i]}
+> @kbd{@}'}
+@print{} 3 3
+@print{} 4 4
+@end example
+
+When sorting an array by element values, if a value happens to be
+a subarray then it is considered to be greater than any string or
+numeric value, regardless of what the subarray itself contains,
+and all subarrays are treated as being equal to each other.  Their 
+order relative to each other is determined by their index strings.
+
+Here are some additional things to bear in mind about sorted
+array traversal.
+
+@itemize @bullet
+@item
+The value of @code{PROCINFO["sorted_in"]} is global. That is, it affects
+all array traversal @code{for} loops.  If you need to change it within your
+own code, you should see if it's defined and save and restore the value:
+
+@example
+@dots{}
+if ("sorted_in" in PROCINFO) @{
+    save_sorted = PROCINFO["sorted_in"]
+    PROCINFO["sorted_in"] = "@@val_str_desc" # or whatever
+@}
+@dots{}
+if (save_sorted)
+    PROCINFO["sorted_in"] = save_sorted
+@end example
+
+@item
+As mentioned, the default array traversal order is represented by
+@code{"@@unsorted"}.  You can also get the default behavior by assigning
+the null string to @code{PROCINFO["sorted_in"]} or by just deleting the
+@code{"sorted_in"} element from the @code{PROCINFO} array with
+the @code{delete} statement.
+(The @code{delete} statement hasn't been described yet; @pxref{Delete}.)

-or ``sort based on comparing the values in descending order.''
-Having to write a simple comparison function for this purpose
-for use in all of your programs becomes tedious.
-For the common simple cases, @command{gawk} provides
-the option of supplying special names that do the requested
-sorting for you.
-You can think of them as ``predefined'' sorting functions,
-if you like, although the names purposely include characters
-that are not valid in real @command{awk} function names.
-
-The following special values are available:
-
-@table @code
-@item "@@ind_str_asc"
-Order by indices compared as strings; this is the most basic sort.
-(Internally, array indices are always strings, so with @samp{a[2*5] = 1}
-the index is @code{"10"} rather than numeric 10.)
-
-@item "@@ind_num_asc"
-Order by indices but force them to be treated as numbers in the process.
-Any index with a non-numeric value will end up positioned as if it were zero. 
-
-@item "@@val_type_asc"
-Order by element values rather than indices.
-Ordering is by the type assigned to the element
-(@pxref{Typing and Comparison}).
-All numeric values come before all string values,
-which in turn come before all subarrays.
-
-@item "@@val_str_asc"
-Order by element values rather than by indices.  Scalar values are 
-compared as strings.  Subarrays, if present, come out last.
-
-@item "@@val_num_asc"
-Order by element values rather than by indices.  Scalar values are 
-compared as numbers.  Subarrays, if present, come out last.
-When numeric values are equal, the string values are used to provide
-an ordering: this guarantees consistent results across different
-versions of the C @code{qsort()} function.@footnote{When two elements
-compare as equal, the C @code{qsort()} function does not guarantee
-that they will maintain their original relative order after sorting.
-Using the string value to provide a unique ordering when the numeric
-values are equal ensures that @command{gawk} behaves consistently
-across different environments.}
-
-@item "@@ind_str_desc"
-Reverse order from the most basic sort.
-
-@item "@@ind_num_desc"
-Numeric indices ordered from high to low.
-
-@item "@@val_type_desc"
-Element values, based on type, in descending order.
-
-@item "@@val_str_desc"
-Element values, treated as strings, ordered from high to low.
-Subarrays, if present, come out first.
-
-@item "@@val_num_desc"
-Element values, treated as numbers, ordered from high to low.
-Subarrays, if present, come out first.
-
-@item "@@unsorted"
-Array elements are processed in arbitrary order, which is the normal
-@command{awk} behavior. You can also get the normal behavior by just
-deleting the @code{"sorted_in"} element from the @code{PROCINFO} array,
-if it previously had a value assigned to it.
-@end table
-
-The array traversal order is determined before the @code{for} loop
-starts to run. Changing @code{PROCINFO["sorted_in"]} in the loop body
-will not affect the loop.
-
-For example:
-
-@example
-$ @kbd{gawk 'BEGIN @{}
-> @kbd{   a[4] = 4}
-> @kbd{   a[3] = 3}
-> @kbd{   for (i in a)}
-> @kbd{       print i, a[i]}
-> @kbd{@}'}
-@print{} 4 4
-@print{} 3 3
-$ @kbd{gawk 'BEGIN @{}
-> @kbd{   PROCINFO["sorted_in"] = "@@ind_str_asc"}
-> @kbd{   a[4] = 4}
-> @kbd{   a[3] = 3}
-> @kbd{   for (i in a)}
-> @kbd{       print i, a[i]}
-> @kbd{@}'}
-@print{} 3 3
-@print{} 4 4
-@end example
-
-When sorting an array by element values, if a value happens to be
-a subarray then it is considered to be greater than any string or
-numeric value, regardless of what the subarray itself contains,
-and all subarrays are treated as being equal to each other.  Their 
-order relative to each other is determined by their index strings.
