[FFmpeg-cvslog] doc/texi2pod: add "use warnings" directive

[Stefano Sabatini]

ffmpeg | branch: release/0.11 | Stefano Sabatini <stefasab at gmail.com> | Sun Aug 12 10:35:03 2012 +0200| [e8cae38be6be5c5b258b0fd97d83e30915103685] | committer: Timothy Gu

doc/texi2pod: add "use warnings" directive

The script was previously run with perl -w through the shebang
command. Now that the script is executed through direct perl invocation
the -w in the shebang command is ignored. This patch re-enables "use
warnings" whatever way the script is invoked.
