hm, I don't give any special option to this, so I guess it should be
linked dynamically.

Sounds reasonable (I suppose there have been multiple changes with
threading in glibc between RH 7.3 and RH 8.0, probably even more with
the new thread model in RH 9).

Thanks a lot, I will try this ...

Dear Emily:
	I recently read an article that said, "reply by mail, I'll summarize."
What should I do?

Dear Doubtful:
	Post your response to the whole net.  That request applies only to
dumb people who don't have something interesting to say.  Your postings are
much more worthwhile than other people's, so it would be a waste to reply by
mail.
