[FFmpeg-devel] [PATCH] doc/texi2pod: use env program to detect location of perl interpreter program

[Stefano Sabatini]

Should fix perl detection in case perl is not installed in /usr/bin.

Also use an explicit "use warnings" pragma rather than relying on -w,
since many OS interpret the second part of the shebang line as an unsplit
argument (like "perl -w").
