[FFmpeg-devel] [PATCH 1/3] configure: fix _Pragma check.

[Reimar.Doeffinger at gmx.de]

From: Reimar Döffinger <Reimar.Doeffinger at gmx.de>

The test can current pass when _Pragma is not supported, since
_Pragma might be treated as a implicitly declared function.
This happens e.g. with tinycc.
Extending the check to 2 pragmas both matches the actual use
better and avoids this misdetection.
