GCC upgrade to 4.9.3 version request

[JiÅÃ Engelthaler <engycz at gmail dot com>]

I would like to request the upgrade GCC to current 4.9.3 version.
4.9.2 version contains invalid code generation issue
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65504) marked with P1
importance which affects also cross compilers generated by 4.9.2
version. In general all binaries compiled with 4.9.2 version should be
rebuild because may be miscompiled.

If you compile this file http://pastebin.com/download.php?i=wvgu8Gz4
with -O2 and without it with 4.9.2 version you will receive different
results.

Also generating cross compiler with 4.9.2 version on Cygwin 32bit will fail.

  len = *entry + 1;
