x264 | branch: master | Henrik Gramner <henrik at gramner.com> | Sun Jan 31 20:21:01 2016 +0100| [5be32efc244d96aa56be462664b5c56d7318e86d] | committer: Henrik Gramner

configure: Define feature test macros for --std=gnu99

Makes the printf() family functions on MinGW use the correct C99 POSIX
versions instead of the broken pre-VS2015 Microsoft ones.

Also allows us to get rid of some _GNU_SOURCE and _ISOC99_SOURCE defines.
