>Description:
When trying to link any program to /opt/SUNWspro/lib/libsunmath.so,
gcc's C++ front end complains as follows:

examples/step-1> cat a.cc
int main () 
{};

This used to work previously. libsunmath, by the way, is Sun's
fortran support library, so you need to link that in if you
want to link your C++ code with F77 code that was compiled
using Sun's Workshop f77 compiler.
