+Subject: [PATCH] cfns: fix mismatch in gnu_inline attributes
+Date: Thu,  6 Aug 2015 23:47:06 -0400
+Message-Id: <1438919226-30427-1-git-send-email-vapier at gentoo.org>
+
+Since the 3.0.3 release of gperf (made in May 2007), the generated func
+has had the gnu_inline attribute applied to it.  The gcc source however
+has not been updated to include that which has lead to a mismatch.
+
+In practice, this hasn't been an issue for two reasons:
+(1) Before gcc-5, the default standard was (gnu) C89, and gcc does not
+warn or throw an error in this mode.
+(2) Starting with gcc-4.8, the compiler driver used to build gcc was
+changed to C++, and g++ does not warn or throw an error in this mode.
+
+This error does show up though when using gcc-5 to build gcc-4.7 or
+older as then the default is (gnu) C11 and the C compiler driver is
+used.  That failure looks like:
+In file included from .../gcc-4.7.4/gcc/cp/except.c:990:0:
+cfns.gperf: At top level:
+cfns.gperf:101:1: error: 'gnu_inline' attribute present on 'libc_name_p'
+cfns.gperf:26:14: error: but not here
+
+Whether the compiler should always emit this error regardless of the
+active standard or compiler driver is debatable (I think it should be
+consistent -- either always do it or never do it).

+	* cfns.gperf [__GNUC__, __GNUC_STDC_INLINE__]: Apply the
