My impression is that Find_Program_Name is broken for

It looks like .exe is the only thing that current targets use.
However, there are configure/Makefile variables to support other
extensions. See ac_exeext in configure. exeext in Makefile. It would
be better if you could compiled in the exeext value instead of assuming
it is .exe.
Thanks Jim.
It is the end of the day and I don't have the EXEEXT part worked in yet
but here is a patch which seems to work correctly for just .exe's.
How does this look?
Would an Ada maintainer please comment on this patch and how they
feel about using EXEEXT since that will require adding some to
sdefault.adb.
