Instead of * checking for OSX and OpenBSD, check for FEATURE_PTHREAD * and use mutex locking unless there is an _r function * available. Better safe than sorry. * * Fixes "./configure --disable-pthread" and should result * in less threading-related problems on pthread-using platforms, * but it still doesn't fix BR#1122404. * * Revision 1.45 2006/08/21 11:15:54 david__schmidt * MS Visual C++ build updates * * Revision 1.44 2006/08/18 16:03:16 david__schmidt * Tweak for OS/2 build happiness. * * Revision 1.43 2006/08/03 02:46:41 david__schmidt * Incorporate Fabian Keil's patch work: * http://www.fabiankeil.de/sourcecode/privoxy/ * * Revision 1.42 2006/07/18 14:48:46 david__schmidt * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch) * with what was really the latest development (the v_3_0_branch branch) * * Revision 1.40.2.4 2005/04/03 20:10:50 david__schmidt * Thanks to Jindrich Makovicka for a race condition fix for the log * file.

Hopefully this will take care of all of those pesky * crash reports. * * Revision 1.40.2.2 2002/09/28 00:30:57 david__schmidt * Update error logging to give sane values for thread IDs on Mach kernels. * It's still a hack, but at least it looks farily normal.
