What is the definition of FLIBS in Makeconf?  I'm guessing it is

   -lgfortranbegin -lgfortran -lm -lgcc_s

Why does it include -lgcc_s?  I think Octave is using the autoconf
macros for determining what Fortran libraries to use, so that might be
a place to start.  Also, how did "-L/opt/csw/lib" end up in the link
flags, and why is the gcc_s library installed there?
