 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
