Recently upgraded my gcc to 4.1.2, from 4.1.1, but Im not sure if initial compilation of this package happened with 4.1.1, but I am sure it happened with gcc4! Also recompiled my system recently with debug useflag set, but dont have enough knowledge to actually tell why it fails to compile.

Have tried disabling/enabling every use flag too, just to be complete, but without a differnce... Although it looks like compiler problem.

Reproducible: Always

Steps to Reproduce:
1. emerge snes9x
2.
3.

Created attachment 113454 [details, diff]
patch that fixes compilation errors

Ebuild installs succesfully with this patch; applied & tested myself. Hope this helps!

[Comment 2 Sascha Hlusiak 2007-05-22 01:41:22 UTC]

Patch worked for me. 
I suggest to include this patch as fast as possible in portage, because 1.43-r1 is marked stable, it's the only available version in the tree right now and upcoming version 1.51 has some regressions.

[Comment 3 OxO pHz.60 2007-07-10 19:38:44 UTC]

I have the same problem on x86_64...
