Just checked it and it works with GNU f77 (gcc version 2.95.3) on FreeBSD.

As an alternative :

If you are building from source then there is a '-fno-underscoring' option
to f77 which stops two underscores being added if the name contains an
underscore.  You may want to check the program builds and links properly
without the option before trying it, especially if the program links to
non-Fortran code.

Ian.
