On Ultrix, the Fortran compiler expects registers 2 through 5 to be saved
by function calls. However, the C compiler uses conventions compatible
with BSD Unix: registers 2 through 5 may be clobbered by function calls.
GCC uses the same convention as the Ultrix C compiler. You can use
these options to produce code compatible with the Fortran compiler:
