Hi'all,

Solved the problem with Winchip not booting. It turns out they do not like the
code generated by gcc (gcc version 2.95.2 19991024 (release)) when the
-march=i686 flag is set. Changing this flag to -march=i586 makes to box boot
like it should.

I do not have a working egcs 1.1.x or gcc 2.7.2x here, but I presume they DO
produce working code, if only because the earlier compilers lacked specific
support for pentium and above. It seems the arch/i386/Makefile is incorrect in
stating that these Winchips are in fact i686 compatible, or it might be that
gcc does bad things to these processors. Anyway, included is a small patch to
solve these problems with Winchips.

Cheers//Frank
