>Description:
graphics/libepoxy is again broken on Solaris:

  CC       dispatch_common.lo
dispatch_common.c: In function 'epoxy_get_proc_address':
dispatch_common.c:676:1: error: control reaches end of non-void function [-Werror=return-type]
 }
 ^

I don't understand when and how this problem was introduced, I was able to build version 1.3.1 of libepoxy a few days ago, and the recent Darwin-related changes look unsuspicious.

I can build this package on NetBSD 7.0 R2 with GCC 4.8.4 (and "PKG_OPTIONS.MesaLib = -dri -llvm", i.e. without EGL), but it fails on Solaris 11.2 with GCC 4.8.5 - no matter if MesaLib was built with or without EGL.
