gnome upstream and gnome herd doesn't support optimization level above 2 (-Os and -O3). Please try again with safer CFLAGS (-O2 -march=native -pipe)

re-emerge it without the debug use flag. That sets -pedantic -ansi, which causes the build to fail on the (otherwise perfectly valid) C++ style comment at that line.

CFLAGS such as -pedantic or -Werror should _never_ be included in official release tarballs. It's just plain dumb. You can't predict what compilers your users are going to use 2 weeks or 6 months from when the tarball is released. We try as much as we can to convince upstream devs to remove such flags, most of them understand. I guess we'll have to file a bug upstream about this. Thanks
More importantly, the debug use flag probably doesn't do what you think it does. We need to remove it from almost all gnome packages; currently, it's in the eclass, and breaks all kinds of things. Here's the description of the debug use flag: debug - Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see http://www.gentoo.org/proj/en/qa/backtraces.xml
Ah, I'm glad that somebody found a solution to this. I thought I would need to submit a patch to gnome ;-) Given that the package is marked ~x86 (as of a few days ago anyway) it's not so bad that it won't compile with +debug. Thanks for pointing out a work-around.

thanks for the bug report, doing what the bug report describes fixed the compile failures for me also (had debug also in my use flags), Alex
I've stripped off the silly flags, fix is in tree.
