Re: [Gcl-devel] Re: OpenBSD progress

[Camm Maguire]

Greetings, and thank you so much for your work on this!

In brief, I've committed what I believe to be equivalents to your
patches in both branches.  Please confirm that gcl compiles out of the
box for you, or let me know what needed changes may remain.

I have dropped this, as several ports do rely on dlopen, and I don't
have time to test right now.  In general, our configure.in logic is
very convoluted and needs cleaning.  I haven't the time at the moment,
alas.  These temporary variables (i.e. TLIBS) were put in at some
point to step around the automatic operation of the autoconf macros
where required.  The whole situation needs revisiting in 2.7.x.

I've committed this as it appears to work OK, but do you really need
it?  I thought the main fix here for you was -Z.  In general, I'd
prefer to stay away from partial merges against CVS snapshots unless
required.

Great!  And I confirm on Debian unstable i386.  Will upload a new
Debian package to double check, but I anticipate no difficulties.

This is always a moving target given Paul's fine work, but it sounds
in the ballpark.  Stable branch failures are 304 if you'd like to
double check.

Great!

Yes!

axiom?
