The gfortran compiler is relatively new. Earlier versions of GCC shipped

only a Fortran 77 compiler, called with g77.

Thanks for the tip. I already discovered that we have version 2.95.1

of gcc with g77. The previous problems vanished, however the new

problems occured. Do you have any ideas about this:

Standard C++, the topic of this newsgroup, has no means of communicating

with fortran. Since you are using both the GNU C++ and the GNU fortran

compilers (?), I suggest you ask in a GNU forum.

I probably will.
