x11-base/xorg-server-1.7.6 has no requirement for gcc >= 4, but seems to contain a gcc4'ism in sdksyms.c, which fails to compile. Some select error messages: sdksyms.c:391: error: syntax error before "void" sdksyms.c:401: error: syntax error before "int" The corresponding lines in sdksyms.c read: (void *) &void, ... (void *) &int, The problem seems to be the awk statement in sdksyms.sh that generates sdksyms.c, which assumes gcc4 preprocessor output. If forcing cpp-4.3.4, everything is fine, but with cpp-3.4.6, it fails: loader # rm sdksyms.c; make CPP=cpp-4.3.4 CC sdksyms.o sdksyms.c:2: warning: ignoring #pragma GCC diagnostic sdksyms.c:774: warning: `SecurityLookupIDByType' is deprecated (declared at ../../../include/resource.h:265) sdksyms.c:775: warning: `SecurityLookupIDByClass' is deprecated (declared at ../../../include/resource.h:272) sdksyms.c:776: warning: `LookupIDByType' is deprecated (declared at ../../../include/resource.h:277) sdksyms.c:777: warning: `LookupIDByClass' is deprecated (declared at ../../../include/resource.h:282) sdksyms.c:1493: warning: `miPointerCurrentScreen' is deprecated (declared at ../../../mi/mipointer.h:116) LINK libloader.la loader # rm sdksyms.c;

As far as I know, this used to work in earlier versions of xorg-server.
We could maybe add a gcc-3 check to the ebuild, but the actual compile fix should be implemented upstream. Please visit https://bugs.freedesktop.org/ and report a bug there if none already exists, then post the url here.
Resolving NEEDINFO, please reopen when you can give the upstream bug url.
