+# SYNOPSIS
+#
+#   AX_CHECK_DOS_FILESYS_LIMITATIONS
+#
+# DESCRIPTION
+#
+#   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 AX_CHECK_PATHNAME_STYLE_DOS.
