I am seeing this compile warning in plperl:

gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -fno-strict-aliasing
-O1 -Wall -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith
-Wcast-align -fpic -I. -I../../../src/include

plperl.c: In function `plperl_spi_query':

plperl.c:1622: warning: passing arg 1 of `Perl_newSVpv' discards
qualifiers from pointer target type

Is anyone else seeing this? This is with:

No, because we're all using less obsolete Perls ;-). Evidently they
added the const qualifier to newSVpv's declaration since then.

Perl 5.6 was released more than 5 years ago now, I think that we could
reasonably say that it is the minumum version we support.

OTOH:
. I am seeing LOTS of warnings (not for plperl) about mismatched
signedness of things
. David Fetter has shown me another plperl warning (this time at
runtime) that I'm on the track of

Yeah, the multibyte code is just full of places where "char *" is passed
to "unsigned char *" or vice versa. It's harmless, but on compilers
that warn about that (which includes the latest gcc releases) it's
pretty annoying. Sometime we'll have to clean it up.
