1997.05.12 02:41 "FreeBSD shared-library", by Richard Mlynarik

I've fixed what seems to be an obvious bug in Linux shared-library building, but I'm in no position to test it. It looks like it would never have worked.

I'd guess that code nearly-identical to the freebsd stuff would work for BSDI and NetBSD; I'm not able to verify this, either.

It would be nice if the mailing list archives in ftp://ftp.sgi.com/graphics/tiff/archives/ were maintained; I don't have time to be on a mailing list, but it would be nice to be able to search for things when I cared.
