Debian/m68k gcj

[Thorsten Glaser <tg@mirbsd.de>]

Hi all,

I’ve built and uploaded gettext (sorry for the unfortunate version
numbering – it’s in fact a binNMU built from unmodified sources)
and db4.8 to unstable with a gcj recompiled against a patched eglibc.
(This gcj ended up in unreleased because I added a patch to have
the sem_wait error printed, except it’s probably no longer needed,
but feeding it upstream might be a good idea nevertheless; attached.)

This means my request to drop Java™ support for m68k on these pak-
kages has been superseded.

As for db4.7, there’s the other build error, but as it’s been
orphaned I’m going to search for it, hopefully fix it and do a
QA upload. (Why does e.g. Perl still depend on it, anyway?)

Still not quite back from VAC (gimme today and tomorrow to catch
up) but back with internet access, if you wondered…

bye,
//mirabilos
