[ID 20000318.004] [PATCH perl.c 5.6RC2] Duplicate SITELIB_STEMand SITELIB_EXP

This is a bug report for perl from schwern@pobox.com,
generated with the help of perlbug 1.27 running under perl v5.6.0.


-----------------------------------------------------------------
[Please enter your report here]

I usually remove the version specific subdirectory off of the site lib
path when I configure, gets in the way more often than not (of course,
the new extra @INC feature dampens this somewhat).  Anyhow, currently
if site lib is something like: /usr/lib/perl5/site_perl/ (instead of
/usr/lib/perl5/site_perl/5.6) the SITELIB_STEM will come out the same,
thus you'll have duplicate directory entries in @INC.

This patch notes and fixes this problem, though perhaps it would be
better to handle at the point where config.h is built.

Of course, this can wait until after 5.6.0
