Title: Patch pcre to pass all tests when compiled with GCC 4.9.

Pcre failed to pass one test when compiled with GCC 4.9.
Patch taken from Fedora, original url is
http://pkgs.fedoraproject.org/cgit/pcre.git/plain/pcre-8.35-Do-not-rely-on-wrapping-signed-integer-while-parsein.patch
Checked on Linux 64-bit with GCC 4.7, 4.8, 4.9, Clang 3.5 - all good.
