-This patch was taken from https://gcc.gnu.org/ml/gcc-patches/2015-08/msg00375.html.
-It is used by propeller-gcc-4.
-
-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).
