_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.
