Assuming there's a non-underline version of the same file name, the
underline versions have been run through cpp (C Pre Processor) to
handle preprocessing directives like "#ifdef MPI". Fortran did not
do such preprocessing when I wrote the portable compilation system
for Amber, so I coded it explicitly, using these intermediate files.
The underlined files are then compiled by the fortran compiler.
