 Maybe we can forget all about my bug report if one could tell me if
 it should matter if I specify march/mcpu options in cc1_options
 instead of cc1_cpu in the spec file. If this really matters then it
 should be documented somewhere I think. I had these options appended
 to cc1_options. If I move'em to cc1_cpu the problems go away.
 
 The -fomit-frame-pointer issue was already reported and there is an
 patch floating around. (http://gcc.gnu.org/ml/gcc/2002-07/msg00367.html)
 which I haven't tried yet.
