[Stefano Sabatini]

ffmpeg | branch: master | Stefano Sabatini <stefasab at gmail.com> | Sun Aug 12 10:35:03 2012 +0200| [3239382aefd0f5fa9ffd1509ccaedd59a54ec9af] | committer: Stefano Sabatini

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.
