330 compilations warnings building Perl

I just built perl after a few weeks of not pulling. We have a *ridiculous*
number of warnings during compilation. 330 to be exact. IMO that is *WAY*
too many.

Some of them appear to be serious. IMO all of them should have been
silenced before being merged.

If module authors are releasing code full of warnings then a requirement
for them being in core should be that they are more or less warning free.

Similarly if core developers are hacking on stuff they should make sure
their code is warning free before merging. I have to admit to being
surprised that I am the first to notice.

Perhaps we need to get the smokers to include warning counts, and maybe set
up some kind of way to alert when the number of warnings jumps
significantly.

This report is from compiling ed996a54e9e136efd3812a9f2d00d7102ed0ef1a

cheers,
Yves
