No. I was using threads well before 2.0 came out. Threading libraries *do*

No. apr_hints is a last resort. Actual tests like the AC_TRY_COMPILE() that
Justin did are the right way to do it. We should always try to avoid
hard-coding conditions to the host/library/whatever and *test* for them

autoconf was written to use the testing approach, rather than the "know
everything about all platforms" approach that Apache 1.3 used. apr_hints is
left over from the 1.3 days; ideally, we would find tests that would remove
every single one of those hints.
