+	* awkgram.y (install_builtins): If do_traditional is true, do not
+	install gawk extensions flagged with GAWKX.  Similarly, if do_posix
+	is true, do not install functions flagged with NOT_POSIX.
+	This fixes a problem with spurious lint complaints about shadowing
+	a global variable that is not valid in traditional or posix mode.
+	Thanks to Andrew Schorr for finding the problem and supplying
+	initial code; I did it slightly differently.

+
+	* symbol.c (check_param_names): Fix argument order in memset() call.

+	regexec.c: Sync with GLIBC. Mostly copyright date updates.
+
+2015-02-05         Andrew J. Schorr     <aschorr@telemetry-investments.com>
+
+	* eval.c (set_IGNORECASE): If IGNORECASE has a numeric value, try
+	using that before treating it as a string.  This fixes a problem
+	where setting -v IGNORECASE=0 on the command line was not working
+	properly.
+
+2015-02-01         Arnold D. Robbins     <arnold@skeeve.com>
+
+	Move POSIX requirement for disallowing paramater names with the
+	same name as a function into --posix.
+
+	* NEWS: Document it.
+	* awkgram.y (parse_program): Check do_posix before calling
+	check_param_names().
+	* symbol.c (check_param_names): Set up a fake node and call
+	in_array() for function parameter names instead of linear
+	searching the function list a second time. Thanks to Andrew
+	Schorr for the motivation.
+
+2015-01-30         Arnold D. Robbins     <arnold@skeeve.com>
+
+	Don't allow function parameter names to be the same as function
+	names - required by POSIX. Bug first reported in comp.lang.awk.
+
+	In addition, don't allow use of a parameter as a function name
+	in a call (but it's ok in indirect calls).
+
+	* NEWS: Updated.
+	* awk.h (check_param_names): Add declaration.

+	should be created when lookup is called, not when update is called.
+	* awk.h (variable_create): Remove function declaration.
+	* awkgram.y (variable_create): Remove function.
+	(variable): Restore variable_create functionality inline.
+	* gawkapi.c (api_sym_update): Revert to using install_symbol, since the

+
+2015-01-07         Andrew J. Schorr     <aschorr@telemetry-investments.com>

+	whether this is a deferred variable.
+	* awkgram.y (variable_create): Return indicator of whether this is
+	a deferred variable in a newly added 3rd arg.
+	(variable): Pass 3rd arg to variable_create.
+	* gawkapi.c (api_sym_update): If we triggered the creation of a deferred
+	variable, we must merge the extension's array elements into the deffered
+	array, not the other way around.  The ENVIRON array has special funcs
+	to call setenv and unsetenv.
+

+
+	* awk.h (variable_create): Declare new function.
+	* awkgram.y (variable_create): New function to create a variable
+	taking the deferred variable list into consideration.
+	(variable): Call new function variable_create if the variable is
+	not found.
+	* gawkapi.c (api_sym_update): If an array is being created, then
+	call new function variable_create instead of install_symbol.  If this
+	is the first reference to a deferred variable, than the new array
+	may contain elements that must be merged into the array provided by
+	the extension.
+
+2015-01-05         Andrew J. Schorr     <aschorr@telemetry-investments.com>
+
+	* io.c (wait_any): If the `interesting' argument is non-zero, then we
+	must not return until that child process has exited, since the caller
+	gawk_pclose depends on our returning its exit status.  So in that case,
+	do not pass WNOHANG to waitpid.

+	Enable non-fatal output on per-file or global basis,

+5.10 Enabling Nonfatal Output
+=============================
+
+This minor node describes a `gawk'-specific feature.
+
+   In standard `awk', output with `print' or `printf' to a nonexistent
+file, or some other I/O error (such as filling up the disk) is a fatal
+error.
+
+     $ gawk 'BEGIN { print "hi" > "/no/such/file" }'
+     error--> gawk: cmd. line:1: fatal: can't redirect to `/no/such/file' (No such file or directory)
+
+   `gawk' makes it possible to detect that an error has occurred,
+allowing you to possibly recover from the error, or at least print an
+error message of your choosing before exiting.  You can do this in one
+of two ways:
+
+   * For all output files, by assigning any value to
+     `PROCINFO["NONFATAL"]'.
+
+   * On a per-file basis, by assigning any value to `PROCINFO[FILENAME,
+     "NONFATAL"]'.  Here, FILENAME is the name of the file to which you
+     wish output to be nonfatal.
+
+   Once you have enabled nonfatal output, you must check `ERRNO' after
+every relevant `print' or `printf' statement to see if something went
+wrong.  It is also a good idea to initialize `ERRNO' to zero before
+attempting the output. For example:
+
+     $ gawk '
+     > BEGIN {
+     >     PROCINFO["NONFATAL"] = 1
+     >     ERRNO = 0
+     >     print "hi" > "/no/such/file"
+     >     if (ERRNO) {
+     >         print("Output failed:", ERRNO) > "/dev/stderr"
+     >         exit 1
+     >     }
+     > }'
+     error--> Output failed: No such file or directory
+
+   Here, `gawk' did not produce a fatal error; instead it let the `awk'
+program code detect the problem and handle it.
+
+   This mechanism works also for standard output and standard error.
+For standard output, you may use `PROCINFO["-", "NONFATAL"]' or
+`PROCINFO["/dev/stdout", "NONFATAL"]'.  For standard error, use
+`PROCINFO["/dev/stderr", "NONFATAL"]'.
+
+   When attempting to open a TCP/IP socket (*note TCP/IP Networking::),
+`gawk' tries multiple times. The `GAWK_SOCK_RETRIES' environment
+variable (*note Other Environment Variables::) allows you to override
+`gawk''s builtin default number of attempts.  However, once nonfatal
+I/O is enabled for a given socket, `gawk' only retries once, relying on
+`awk'-level code to notice that there was a problem.

+
+     In the usual case, the extension is interested in `(*ibufp)->fd'

+     to notice that neither the `fd' in the returned `awk_input_buf_t'
+     nor the `fd' in the returned `awk_output_buf_t' matches the
+     requested value.
+
+     Note that supplying a file descriptor is currently _not_ supported
+     for pipes.  However, supplying a file descriptor should work for
+     input, output, append, and two-way (coprocess) sockets.  If
+     `filetype' is two-way, `gawk' assumes that it is a socket!  Note
+     that in the two-way case, the input and output file descriptors
+     may differ.  To check for success, you must check whether either
+     matches.

      machine-executable object code.  The object code is then executed
      directly by the computer.  See also "Interpreter."
 
+Complemented Bracket Expression
+     The negation of a "bracket expression".  All that is _not_
+     described by a given bracket expression. The symbol `^' precedes
+     the negated bracket expression.  E.g.: `[[^:digit:]' designates
+     whatever character is not a digit. `[^bad]' designates whatever
+     character is not one of the letters `b', `a', or `d'.  See

+@section Enabling Nonfatal Output
+
+This @value{SECTION} describes a @command{gawk}-specific feature.
+
+In standard @command{awk}, output with @code{print} or @code{printf}
+to a nonexistent file, or some other I/O error (such as filling up the
+disk) is a fatal error.
+
+@example
+$ @kbd{gawk 'BEGIN @{ print "hi" > "/no/such/file" @}'}
+@error{} gawk: cmd. line:1: fatal: can't redirect to `/no/such/file' (No such file or directory)
+@end example
+
+@command{gawk} makes it possible to detect that an error has
+occurred, allowing you to possibly recover from the error, or
+at least print an error message of your choosing before exiting.
+You can do this in one of two ways:
+
+@itemize @bullet
+@item
+For all output files, by assigning any value to @code{PROCINFO["NONFATAL"]}.
+
+@item
+On a per-file basis, by assigning any value to
+@code{PROCINFO[@var{filename}, "NONFATAL"]}.
+Here, @var{filename} is the name of the file to which
+you wish output to be nonfatal.
+@end itemize
+
+Once you have enabled nonfatal output, you must check @code{ERRNO}
+after every relevant @code{print} or @code{printf} statement to
+see if something went wrong.  It is also a good idea to initialize
+@code{ERRNO} to zero before attempting the output. For example:
+
+@example
+$ @kbd{gawk '}
+> @kbd{BEGIN @{}
+> @kbd{    PROCINFO["NONFATAL"] = 1}
+> @kbd{    ERRNO = 0}
+> @kbd{    print "hi" > "/no/such/file"}
+> @kbd{    if (ERRNO) @{}
+> @kbd{        print("Output failed:", ERRNO) > "/dev/stderr"}
+> @kbd{        exit 1}
+> @kbd{    @}}
+> @kbd{@}'}
+@error{} Output failed: No such file or directory
+@end example
+
+Here, @command{gawk} did not produce a fatal error; instead
+it let the @command{awk} program code detect the problem and handle it.
+
+This mechanism works also for standard output and standard error.
+For standard output, you may use @code{PROCINFO["-", "NONFATAL"]}
+or @code{PROCINFO["/dev/stdout", "NONFATAL"]}.  For standard error, use
+@code{PROCINFO["/dev/stderr", "NONFATAL"]}.
+
+When attempting to open a TCP/IP socket (@pxref{TCP/IP Networking}),
+@command{gawk} tries multiple times. The @env{GAWK_SOCK_RETRIES}
+environment variable (@pxref{Other Environment Variables}) allows you to
+override @command{gawk}'s builtin default number of attempts.  However,
+once nonfatal I/O is enabled for a given socket, @command{gawk} only
+retries once, relying on @command{awk}-level code to notice that there
+was a problem.

+in the @code{ibufp} and @code{obufp} pointers.  For input

+should be @code{NULL}.  For two-way coprocesses, both values should
+be non-@code{NULL}.
+
+In the usual case, the extension is interested in @code{(*ibufp)->fd}
+and/or @code{fileno((*obufp)->fp)}.  If the file is not already
+open, and the @code{fd} argument is non-negative, @command{gawk}

+usual way.  If @code{fd} is non-negative, but the file exists already,
+@command{gawk} ignores @code{fd} and returns the existing file.  It is
+the caller's responsibility to notice that neither the @code{fd} in
+the returned @code{awk_input_buf_t} nor the @code{fd} in the returned
+@code{awk_output_buf_t} matches the requested value.
+
+Note that supplying a file descriptor is currently @emph{not} supported
+for pipes.  However, supplying a file descriptor should work for input,
+output, append, and two-way (coprocess) sockets.  If @code{filetype}
+is two-way, @command{gawk} assumes that it is a socket!  Note that in
+the two-way case, the input and output file descriptors may differ.
+To check for success, you must check whether either matches.

+@section Enabling Nonfatal Output
+
+This @value{SECTION} describes a @command{gawk}-specific feature.
+
+In standard @command{awk}, output with @code{print} or @code{printf}
+to a nonexistent file, or some other I/O error (such as filling up the
+disk) is a fatal error.
+
+@example
+$ @kbd{gawk 'BEGIN @{ print "hi" > "/no/such/file" @}'}
+@error{} gawk: cmd. line:1: fatal: can't redirect to `/no/such/file' (No such file or directory)
+@end example
+
+@command{gawk} makes it possible to detect that an error has
+occurred, allowing you to possibly recover from the error, or
+at least print an error message of your choosing before exiting.
+You can do this in one of two ways:
+
+@itemize @bullet
+@item
+For all output files, by assigning any value to @code{PROCINFO["NONFATAL"]}.
+
+@item
+On a per-file basis, by assigning any value to
+@code{PROCINFO[@var{filename}, "NONFATAL"]}.
+Here, @var{filename} is the name of the file to which
+you wish output to be nonfatal.
+@end itemize
+
+Once you have enabled nonfatal output, you must check @code{ERRNO}
+after every relevant @code{print} or @code{printf} statement to
+see if something went wrong.  It is also a good idea to initialize
+@code{ERRNO} to zero before attempting the output. For example:
+
+@example
+$ @kbd{gawk '}
+> @kbd{BEGIN @{}
+> @kbd{    PROCINFO["NONFATAL"] = 1}
+> @kbd{    ERRNO = 0}
+> @kbd{    print "hi" > "/no/such/file"}
+> @kbd{    if (ERRNO) @{}
+> @kbd{        print("Output failed:", ERRNO) > "/dev/stderr"}
+> @kbd{        exit 1}
+> @kbd{    @}}
+> @kbd{@}'}
+@error{} Output failed: No such file or directory
+@end example
+
+Here, @command{gawk} did not produce a fatal error; instead
+it let the @command{awk} program code detect the problem and handle it.
+
+This mechanism works also for standard output and standard error.
+For standard output, you may use @code{PROCINFO["-", "NONFATAL"]}
+or @code{PROCINFO["/dev/stdout", "NONFATAL"]}.  For standard error, use
+@code{PROCINFO["/dev/stderr", "NONFATAL"]}.
+
+When attempting to open a TCP/IP socket (@pxref{TCP/IP Networking}),
+@command{gawk} tries multiple times. The @env{GAWK_SOCK_RETRIES}
+environment variable (@pxref{Other Environment Variables}) allows you to
+override @command{gawk}'s builtin default number of attempts.  However,
+once nonfatal I/O is enabled for a given socket, @command{gawk} only
+retries once, relying on @command{awk}-level code to notice that there
+was a problem.

+On error, return a @code{false} value.  Otherwise, return

+in the @code{ibufp} and @code{obufp} pointers.  For input

+be non-@code{NULL}.

+In the usual case, the extension is interested in @code{(*ibufp)->fd}
+and/or @code{fileno((*obufp)->fp)}.  If the file is not already
+open, and the @code{fd} argument is non-negative, @command{gawk}

+the caller's responsibility to notice that neither the @code{fd} in
+the returned @code{awk_input_buf_t} nor the @code{fd} in the returned
+@code{awk_output_buf_t} matches the requested value.
+
+Note that supplying a file descriptor is currently @emph{not} supported
+for pipes.  However, supplying a file descriptor should work for input,
+output, append, and two-way (coprocess) sockets.  If @code{filetype}
+is two-way, @command{gawk} assumes that it is a socket!  Note that in
+the two-way case, the input and output file descriptors may differ.

-
-dnl Macro to add for using GNU gettext.
-
-dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
-dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
-dnl    default (if it is not specified or empty) is 'no-libtool'.
-dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
-dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
-dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
-dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
-dnl    depending on --{enable,disable}-{shared,static} and on the presence of
-dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
-dnl    $(top_builddir)/intl/libintl.a will be created.
-dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
-dnl    implementations (in libc or libintl) without the ngettext() function
-dnl    will be ignored.  If NEEDSYMBOL is specified and is
-dnl    'need-formatstring-macros', then GNU gettext implementations that don't
-dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
-dnl INTLDIR is used to find the intl libraries.  If empty,
-dnl    the value `$(top_builddir)/intl/' is used.
-dnl
-dnl The result of the configuration is one of three cases:
-dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
-dnl    and used.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 2) GNU gettext has been found in the system's C library.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 3) No internationalization, always use English msgid.
-dnl    Catalog format: none
-dnl    Catalog extension: none
-dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
-dnl The use of .gmo is historical (it was needed to avoid overwriting the
-dnl GNU format catalogs when building on a platform with an X/Open gettext),
-dnl but we keep it in order not to force irrelevant filename changes on the
-dnl maintainers.
