When I compile Perl on x86_64 Linux I get numerous gcc "limited range of datatype" warnings that show up as: 
regexec.c: In function `S_regtry':
regexec.c:2166: warning: comparison is always false due to limited ran
+ge of data type
regexec.c:2168: warning: comparison is always false due to limited ran
+ge of data type

I get this when I compile the 5.8.7 source tarball and Red Hat's 5.8.5 SRPM. My questions are:
  1. is there anyway to fix these comparisons?
  2. if not, are these warnings something to be concerned about?
  3. if yes, is Perl recommended on x86_64, or not really?
Thanks,
John
