This is the preprocessed source output the compiler told me to attach here

Comment 2 Jakub Jelinek 2004-02-25 16:05:09 UTC
You cannot use -march=pentiumpro in 64-bit mode (i686 doesn't have
x86-64 instructions).
I'll add following patch (something similar is already in GCC 3.4+):
2004-02-25  Jakub Jelinek  <jakub>

        * config/i386/i386.c (override_options): Error if -m64 and selected
        processor doesn't support x86-64 instruction set.
