ffmpeg | branch: master | Diego Biurrun <diego at biurrun.de> | Fri Aug  2 22:03:09 2013 +0200| [038c4f65ee6c72f9d1ee4d4e46c74073992fabc8] | committer: Michael Niedermayer

configure: Check for GCC diagnostic pragma support inside of functions

The actual usage of the pragma is within functions and older versions
of gcc only support the pragma outside of functions.
