plperl warning

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-I/usr/local/include/readline
-I/usr/contrib/include-I/usr/libdata/perl5/5.00503/i386-bsdos/CORE -c -o plperl.o plperl.cplperl.c: In function
`plperl_spi_query':plperl.c:1622:warning: passing arg 1 of `Perl_newSVpv' discardsqualifiers from pointer target type
 

Is anyone else seeing this?  This is with:
