System: FreeBSD database.westbend.net 5.1-CURRENT FreeBSD 5.1-CURRENT #5: Tue Aug 19 12:12:38 CDT 2003     root at current.westbend.net:/usr/obj/usr/src/C/sys/WB  i386

>Description:
	-CURRENT's gcc no longer has the -pthreads flags.  With this removal of -pthreads,
	ports that try to detect the threads libraries will no longer compile on -CURRENT
	with threads support.

>How-To-Repeat:
	Try to compile security/amavisd as follows:

	    make -DWITH_MILTER build
>Fix:
	Apply the following patch to bsd.port.mk.

	NOTE: This will only fix the ports that have configure scripts that check the
	      value of PTHREAD_{CFLAGS,LIBS} for the thread library to use.
