Description of problem:

>  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.

>  By removing some if/then/else logic, to make it just eval() the 32-bit
>  case, the problem went away.

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
