Why are you using -msse2 together with -march=pentium3? SSE2 is a P4 feature, you probably want -msse.
Could you try recompiling after removing -msse2? If that doesn't work, please try -march=i686.

[Comment 3 Sebastian Bergmann (RETIRED) 2004-07-16 02:33:57 UTC]

CFLAGS="-pipe -march=pentium3 -msse2 -O2 -fomit-frame-pointer" was recommended to me for Pentium M CPUs (on either the gentoo-user mailinglist or one of the Gentoo IRC channels). /proc/cpuinfo shows "fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 tm pbe tm2 est" for my CPU, so sse2 should be okay.

But you are right: after removing -msse2 from my CFLAGS app-emulation/uae-0.8.25_pre20040302 merges without problems.

[Comment 4 David Holm (RETIRED) 2004-07-16 06:25:58 UTC]

I see. It's possible that -msse2 either triggers a bug in GCC related to UAE or that it is incompatible with the build in some other way. I added strip-flags in the ebuild in order to remove -msse and -msse2. I hope this will fix this issue.
