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