x86_64 "limited range of datatype" warning
When I compile Perl on x86_64 Linux I get numerous gcc "limited range of datatype" errors that show up as:
John
regexec.c: In function `S_regtry': regexec.c:2166: warning: comparison is always false due to limited range of data type regexec.c:2168: warning: comparison is always false due to limited range of data typeI get this when I compile from the 5.8.7 source tarball and Red Hat's 5.8.5 SRPM. My questions are:
- is there anyway to fix these comparisons?
- if not, are these warnings something to be concerned about?
- if yes, is Perl recommended on x86_64, or not really?

1. is there anyway to fix these comparisons?
Not easily.
2. if not, are these warnings something to be concerned about?
No, they are harmless.
3. if yes, is Perl recommended on x86_64, or not really?
Perl is fine on that platform. It's currently my main platform for developing perl.
