Subject: Fix up Linux hints for tcsh, and Configure patch
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=1eb1b1cb9647b817d039bb17afa3e74940b5ef92;p=p5sagit%2Fp5-mst-13.2.git

Fix up Linux hints for tcsh, and Configure patch

perl5.003_97[mumble,mumble] contained some hints to work around a csh bug
in some versions of Linux.

Unfortunately, that hint doesn't work for a variety of reasons.  If
anyone's really interested in the anatomy of a failed hint, I can oblige.
Or you can just trust me :-)
