Did anyone object to them last time, or did they just fall through the
If the latter would you be willing to check the patches against current and
attach them to a PR? I'll see if anyone objects to getting them committed.

OK, then possibly we should return to this after the other issues are

Presumably you have some staticly linked threaded apps running fine?

If they do not break anything else, then get them in.

The goal is for you to stop having to do some of these changes time every
timeyou update to a new version, plus to get them into the hands of other
people who could find them useful. If no-one else would benefit from them
then maybe they are best off just in your local tree, but hopefully someone
will pipe up and offer to help...

Maybe you could pick some of the smaller changes and look at porting them
forward to current. I'd certainly think I18N seems to be a good place to
start, plus pkgsrc changes which are pretty much OS version neutral.
