Configure of x11-drivers/xf86-video-ati-7.4.0::gentoo[glamor] fails due to inproper include ordering. Results in HAVE_STRNDUP being undefined and " [..] /usr/include/xorg/os.h:579:2: error: expected identifier or '(' before '__exten strndup(const char *str, size_t n); [..] " /usr/include/xorg/os.h:579: " #ifndef HAVE_STRNDUP extern _X_EXPORT char * strndup(const char *str, size_t n); #endif " Already fixed upstream [1], though I'm not sure when there's a new release to be expected including the fix.

Same problem with xf86-input-synaptics. Also fixed upstream master [1], though also no release yet. Using the patch from [1] works for xf86-input-synaptics-1.7.6 (the 1.8+ releases being masked). [1] http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/commit/?id=96e60a4ea242d2decf109835981ae186cc36f642
xf86-video-ati-7.5.0 is in the tree by way of bug 524884
We have versions in the tree that should fix this and are listed in stabilization list from bug 530652
