Glad I could help.

Beats me, looks like a bug in the compiler. It really should
check to see if there is a .exe extension on the -o argument
and add one if not found. But, since there is no way to
rely on this being fixed in autoconf, me thinks we need
to check for the a.out or a.exe. Is there going to be
a problem with compilers other than gcc? Do they
also use a.out or a.exe as the default output name?
