Is there a preferred ordering of the "use" statements at the top?

These changes look fine, but I noticed that the script isn't using strict mode and doesn't have warnings enabled:

- #/usr/bin/perl
+ #/usr/bin/perl -w

These two changes will require all variables to be declared (using 'my').  Sorry I didn't catch this earlier!

No problem -- thanks for noticing it now!

Adding "-w" to the "#!/usr/bin/perl" line actually catches slightly more issues than "use warnings" (IIRC), but I don't think it really matters for this script.

Sorry I missed that part of your comment.  Is "use warnings" redundant with "-w"?  The other Perl scripts seem to have both.

Having both is technically redundant, but doesn't hurt anything.  In this specific case, I think "-w" is equivalent to "use warnings", so it doesn't need both.

See "man warnings" and "man perllexwarn" for details.

http://build.webkit.org/builders/Leopard%20Intel%20Debug%20%28Tests%29/builds/8891 seems to think this change caused a regression.  I don't believe it.

Filed bug 33230 about the failures seen on the bot.  I don't think they're related to this change.
