[PATCH] extern-inline: no need for workaround in GCC 5.1 |

* doc/extern-inline.texi (extern inline):
* m4/extern-inline.m4 (gl_EXTERN_INLINE):
GCC bugs 54113 and 63877 are fixed in GCC 5.1, so don't work
around these bugs in GCC 5.1 and later. Maybe in a decade or
two we can remove these workarounds.

Invoke @code{_GL_INLINE_HEADER_BEGIN} before all uses of
address@hidden in an include file. If an include file includes
address@hidden in an include file. This suppresses some
+bogus warnings in GCC versions before 5.1. If an include file includes
other files, it is better to invoke this macro after including the
other files.
