I finally found time to read the old discussion, and verified that
it does not contain any reason which would justify the a.* pattern.

Thanks for the fix.

When we are at this, the comments in this macro should be reordered.
Attached please find a patch.

Reviews welcome.

Moreover, the order of the file names in ac_files should be fixed,
too:

- "conftest.*" should be at the end of the list, as the comment says.
- "a.out" should be first, beacuse it is the most common output name
  (There is no need to have "a.exe" before it, because Cygwin magic
  is not _that_ clever.)
- "a_out.exe" is not a variant for dos-like systems, it is for
  OpenVMS, as a comment above explains.  So we can safely move it
  near the end.

So the resulting list would be:

ac_files="a.out conftest.exe conftest a.exe a_out.exe b.out conftest.*"

What would you think about this?

Have a nice day,
        Stepan
