I don't mind.  Its just that it is not high priority for me.  I like the
existing GCC predifines better because they provide infornation on newer
chips: pentium2/3/4,  k6, k6-2,k6-3, athlon, athlon-4.  I don't  know
how they all  equate to the _M_IX86 defines.

If this is high priority for you, you will need to provide patchset
against GCC trunk (which will be 3.4 in about 8-9 months time).   Those
lines in the specs file are generated from defines in i386.h in GCC
source. I don't know if Linux and other i386 targets will will want them
so the _M_IX86 definitions may have to go in cygwin.h or mingw.h
