compiler won't generate .o* files when .c file present

This is funny.

heine:> gsc -c matrix-test
heine:> ls -lrt matrix-test.*

No matrix-test.o6! I was pulling my hair out today with some performance problems, because I kept running the interpreted code!

Marc: This seems important, and should be easy to fix, but I don't know how to fix it.

Please consider working on it and fixing it.

Can you debug this and propose a fix? I suspect it is because matrix-test.c exists.

Yes, that's exactly why there's a problem.

Marc, I don't even know in which file to start looking. You probably
know the name of the function that contains the broken logic. It's not
efficient for me to debug this one.

I looked a bit more at this today, but no progress. It does seem to happen only from the command line, (compile-file "foo") generates a new .o file even if foo.c exists.
