Subject Re: prefork and APR_HAS_THREADS
Date Tue, 28 Aug 2007 10:54:31 GMT
IMHO APR_HAS_THREADS has nothing to do with the choice of your MPM (except BEOS).
It only tells you if APR has thread support or not and this only
depends on the platform or if you instructed APR explicitly to build
without thread support.
