ffmpeg | branch: master | Diego Biurrun <diego at biurrun.de> | Tue Nov 22 08:18:38 2016 +0100| [5bcc6f76f180d0f88269018727c92fc562fb8abb] | committer: Diego Biurrun

configure: Disable warning C4703 with MSVC

This disables warnings about potentially uninitialized local pointer
variables.  Disabling the warning is in line with what we do for gcc.
