To a certain extent, I really don't care. :) The Only "problem" is
that autoconf script, "out of the box", are designed to test for a
library 'y' by using '-ly'. This is hard-coded. So to test the library
'pthread' using '-pthread' is kinda akward...

I prefer my hack. :) I think I should write a generic autoconf macro
to test for libs without having '-l' hardcoded...

Sorry (that is before the "no -lc_r" fix but it doesn't change anything..):

Well.. The libtool supplied with the package was _really_
stupid. /usr/local/bin/libtool wasn't that bad. At least it did not
put -lc and -lc_r.
For a program designed to make porting shared libs easy, frankly, that
sucks. :)

Mad. I spent about 15 hours on this thing.

It's there alright.. with no MASTER_SITES! Yeah... That's the last of
the 15 hours... :))
Anyways, thanks for everything
