Ok.

It *should* be possible to mix g77-compiled code with f90-compiled code.
If it isn't, then one or the other compiler writer deserves to be shot.

This is the problem: the file "fortran/ftest.F" isn't being preprocessed
by the C preprocessor to generate the file "fortran/ftest.f".  See my
comments at the end of this message.

You're welcome.  You have a good weekend too.

It appears from the last 5 lines above that the C compiler wasn't able 
to preprocess the file "ftest.F" into the file "ftest.f".  The reason
that the file needs to be preprocessed is to convert macros like
NCSHORT_T into their appropriate Fortran types.  Try executing the
command manually.  Can you get it to work?  Is there some other way to
use the C preprocessor to preprocess the file?  Is there an option to
f90 that will do it?
