-# SYNOPSIS
-#
-#   AX_NORMALIZE_PATH(VARNAME, [REFERENCE_STRING])
-#
-# DESCRIPTION
-#
-#   Perform some cleanups on the value of $VARNAME (interpreted as a path):
-#
-#     - empty paths are changed to '.'
-#     - trailing slashes are removed
-#     - repeated slashes are squeezed except a leading doubled slash '//'
-#       (which might indicate a networked disk on some OS).
-#
-#   REFERENCE_STRING is used to turn '/' into '\' and vice-versa: if
-#   REFERENCE_STRING contains some backslashes, all slashes and backslashes
-#   are turned into backslashes, otherwise they are all turned into slashes.
-#
-#   This makes processing of DOS filenames quite easier, because you can
-#   turn a filename to the Unix notation, make your processing, and turn it
-#   back to original notation.
-#
-#     filename='A:\FOO\\BAR\'
-#     old_filename="$filename"
-#     # Switch to the unix notation
-#     AX_NORMALIZE_PATH([filename], ["/"])
-#     # now we have $filename = 'A:/FOO/BAR' and we can process it as if
-#     # it was a Unix path.  For instance let's say that you want
-#     # to append '/subpath':
-#     filename="$filename/subpath"
-#     # finally switch back to the original notation
-#     AX_NORMALIZE_PATH([filename], ["$old_filename"])
-#     # now $filename equals to 'A:\FOO\BAR\subpath'
-#
-#   One good reason to make all path processing with the unix convention is
-#   that backslashes have a special meaning in many cases. For instance
-#
-#     expr 'A:\FOO' : 'A:\Foo'
-#
-#   will return 0 because the second argument is a regex in which
-#   backslashes have to be backslashed. In other words, to have the two
-#   strings to match you should write this instead:
-#
-#     expr 'A:\Foo' : 'A:\\Foo'
-#
-#   Such behavior makes DOS filenames extremely unpleasant to work with. So
-#   temporary turn your paths to the Unix notation, and revert them to the
-#   original notation after the processing. See the macro
-#   AX_COMPUTE_RELATIVE_PATHS for a concrete example of this.
-#
-#   REFERENCE_STRING defaults to $VARIABLE, this means that slashes will be
-#   converted to backslashes if $VARIABLE already contains some backslashes
-#   (see $thirddir below).
-#
-#     firstdir='/usr/local//share'
-#     seconddir='C:\Program Files\\'
-#     thirddir='C:\home/usr/'
-#     AX_NORMALIZE_PATH([firstdir])
-#     AX_NORMALIZE_PATH([seconddir])
-#     AX_NORMALIZE_PATH([thirddir])
-#     # $firstdir = '/usr/local/share'
-#     # $seconddir = 'C:\Program Files'
-#     # $thirddir = 'C:\home\usr'
