We just got bitten by 32bit vs 64bit logic in the .ph files generated
 from socket.h/stddef.h/limits.h -bits/socket.ph to be exact.
Undefined subroutine &main::__LONG_MAX__ called at (eval 436) line 1.
 Compilation failed in require at
/usr/lib/perl5/5.8.5/i386-linux-thread-multi/sy s/socket.ph line 11.
 Compilation failed in require at
/usr/lib/perl5/site_perl/5.8.5/i386-linux-threa d-multi/netinet/in.ph line
9.
By removing some if/then/else logic, to make it just eval() the 32-bit
 case, the problem went away.
this was after applying an up2date on EL4 for perl 5.8.5:
[ggm@curry log]$ uname -a

fix bug 170088: broken h2ph fixed with h2ph from 5.8.7
fix bug 171111 / upstream bug 37535: IOCPARM_LEN should be _IOC_SIZE
fix bug 172236: make h2ph pick up gcc built-in include directory


Is it possible you haven't tested enough of the outcomes here? Without
 this, the perl just doesn't work.

Version-Release number of selected component (if applicable):
ALL - including RHEL-4 perl-5.8.5-*
not a problem with RHEL-3 perl-5.8.0, because gcc-3.2.3's limits.h #defines
things like __LONG_MAX__
How reproducible:
100%
Steps to Reproduce:
$ perl -e 'require "sys/socket.ph";'
Actual results:
Undefined subroutine &main::__LONG_MAX__ called at (eval 256) line 1.
Compilation failed in require at
/usr/lib/perl5/5.8.6/i386-linux-thread-multi/sys/socket.ph line 11.
Compilation failed in require at -e line 1.
Expected results:
no errors
