The testsuite does return SKIP.  But obviously the test is not working,
and I'd like to change that.  (Even if the failure is known :)

Thanks for this hint.  That's what I needed in order to look into it.

First: the Autoconf check thinks no dummy main is needed.
I still need to find out why it does this.

Second: cprogram.c does not make use of the dummy.
The patch below changes that.  Compiling cprogram by hand then succeeds
if I use
$ make CPPFLAGS=-DF77_DUMMY_MAIN=MAIN__

Is this patch applicable?  Is the idea the right one?
