##### http://autoconf-archive.cryp.to/ac_arg_with_path_style.html # # SYNOPSIS # # AC_ARG_WITH_PATH_STYLE # # DESCRIPTION # # _AC_DEFINE(PATH_STYLE) describing the filesys interface. The value # is numeric, where the basetype is encoded as 16 = dos/win, 32 = # unix, 64 = url/www, 0 = other # # some extra semantics are described in other bits of the value, # especially # # 1024 accepts "/" as a dir separator # 2048 accepts ";" as a path separator # 4096 accepts "," as a path separator # # the macro provides a configure' --with-path-style option that can # be used with descriptive arg names. If not explicitly given, the # $target_os will be checked to provide a sane default. Additional # (lower) bits can be used by the user for some additional magic, # higher bits are reserved for this macro. # # the mnemonic "strict" or "also" is used to instruct the code that # additional seperators shall be accepted but converted to the # seperator of the underlying pathstyle system. (or-512) # # example: --with-path-style=win,slash # to make it accept ";" as pathsep, and # both "/" and "\" as dirseps. # # LAST MODIFICATION # # 2006-10-13 # # COPYLEFT # # Copyright (c) 2006 Guido U.
