This patch allows to compile the 'ustr' package with gcc-5.

Patch copied from Debian:

https://anonscm.debian.org/cgit/users/zito-guest/pkg-ustr.git/commit/?id=fb2528fef188b4de51a27c4f688042c36d2d7a18

From: Václav Ovsík <vaclav.ovsik@gmail.com>
Subject: [PATCH] fixes/gnu-inline

This patch adds `__attribute__ ((gnu_inline))' into prototype macros
before `inline' to force GNU89 behaviour of inline functions
in C99 mode.
See http://www.gnu.org/software/gcc/gcc-5/porting_to.html
