... you must have some concrete examples in mind ...

... can you make those examples ? ;-)

I mean, eg, you're mentioning pthread support ... why would you want to know
that ?  libobjc wraps the local thread library ... maybe you just want to
if threads are available or not (if they're not available, calls to the
thread functions might do nothing or bomb out) ? :-)

At the moment, there is the objc_threaded make variable that you can use
to determine which kind of threading is being used.  Not sure it's considered
public though.  Presumably we could clean it up, give it a public uppercase
name such as GNUSTEP_THREAD_TYPE and here you go ? ;-)

... would that help ?  Probably an example might help. :-)
