ACX_CHECK_DOS_FILESYS_LIMITATIONS
1.1.1.1 (2001/07/26) Miscellaneous @ ac-archive-0.5.39
Mark Elbrecht <snowball3@bigfoot.com>
Check if the target is running on DOS. DOS doesn't allow a dot as the first character, more than one dot, more than eight characters before a dot, and just three letters after the dot. A DOS VM running under Windows 9X does not have these restrictions. A DOS program can be running in either environment, so its important to code accordingly. Defines HAVE_DOS_FILESYS_LIMITATIONS if under DOS.
Use in conjunction with ACX_CHECK_PATHNAME_STYLE_DOS.
