mixing GNU c and FORTRAN

[Twomey, Jack]

Hi,
     I am trying to port an existing program to a SUN workstation that has
the GNU CC compiler (gcc) and GNU FORTRAN compiler (g77).  The existing
program has modules in both languages.  In addition to calls going both
ways, FORTRAN COMMON is accessed in the C modules.  The trailing underscore
method is used to accomplish the interface.  GNU does not seem to accept
this.  Can you direct me to any information on this?
