autoconf CVS: DJGPP & normalization of test results [PATCH]

[Richard Dawe]

Hello.

Below is a patch against autoconf CVS. It adds more substitutions
to the normalization of the test results, to work better with DJGPP:

* strip "exe" extensions;
* strip error codes from DJGPP's error messages, e.g.:

    No such file or directory (ENOENT)

Bye, Rich =]

+       * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): Normalize
+       file name for the m4 program, when it has an "exe" file extension.
+       DJGPP's error messages include the error code in brackets -
+       remove the error code during normalization.
