#
# SYNOPSIS
#
# AX_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 separators shall be accepted but converted to the separator
# of the underlying pathstyle system. (or-512)
#
# example: --with-path-style=win,slash
# to make it accept ";" as pathsep, and
# both "/" and "\" as dirseps.
