You probably managed to use the libF77.a from sun fortran 1.3.  This
is normally located in /usr/lang/SC0.0, and got included because your
environment variable LD_LIBRARY_PATH said to.

The sun library expects the fortran main to be called '_MAIN_'.  The
f2c version of libF77.a expects the fortran main to be called
'_MAIN__'.  To be sure of getting the right libraries, give them a
distinctive name, like libFf2c.a and libIf2c.a, and link with

  'cc ... -L<directory containing f2c libraries> -lFf2c -lIf2c ...'

Hope this helps.
