From 5a57d3d181b82a66e977bfc12cc0b6f6b4ce5a61 Mon Sep 17 00:00:00 2001
From: jlam <jlam>
Date: Wed, 27 Aug 2003 20:43:15 +0000
Subject: (*) Automatically add BUILDLINK_CPPFLAGS.<pkg> and
 BUILDLINK_LDFLAGS.<pkg>,     if they're defined, to the CPPFLAGS and LDFLAGS
 passed to the build.

(*) Fix a silly error that stopped files for "overwrite" packages from
    being symlinked into ${BUILDLINK_DIR} -- a "$" was used instead of "$$".

(*) Normalize a few status messages (printed by ${ECHO_BUILDLINK_MSG}) so
    that they match formats with the rest of pkgsrc.  By default, these
    messages are suppressed.
