_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.
