Supporting the Sun compiler has come up before on this list.  In the GA_F77_LIBRARY_LDFLAGS macro, there is a PUSH/POP macro for replacing CC et al with the unwrapped MPI compilers.  I could have made that more clear since there are a lot of comments about the Sun hack but not the unwrapping hack within the macro itself.
