I believe these two:

> plperl.c:948: warning: `ret_hv' might be used uninitialized in this function
> plperl.c:949: warning: `ret_av' might be used uninitialized in this function

indicate an actual bug --- at least, it's far from clear that the code
can't try to use an uninitialized value. I trust that the authors of
plperl will step up and fix it; I'm not sufficiently clear on what cases
they are trying to support to want to touch it.

The others indicate sloppiness in the C code generated by perl's XS
functionality. There's nothing we can do about them. FWIW, less
obsolete versions of Perl generate fewer warnings --- the only one of
these that I see on 5.8.0 and up is

> SPI.c:158: warning: unused variable `items'
