Sorry, may be a misunderstanding: I am using gcc-3.0.4 to compile
the file z_log.c of libf2c myself, I am not referring to g77 and
libf2c that comes with g77. I need my own version of libf2c for
several reasons (modified variable mappings in the header file f2c.h
and certain other defines in the makefiles deviating from the standard).

OK, now I know that I should probably use "-O2 -ffloat-store" for
the compilation, and not "-O3" or just "-O2" (which I have always
done for previous releases of gcc).

Thanks,

Ulrich
