Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>ACX_CHECK_DOS_FILESYS_LIMITATIONS</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
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.
</p>
<p>
Use in conjunction with ACX_CHECK_PATHNAME_STYLE_DOS.
