[Autoconf] Macro to test for pthreads?

[Bob Friesenhahn]

Does anyone have a tried and proven macro they can point me to that
updates LIBS, CPPFLAGS, and CFLAGS values to support POSIX threads
across platforms?  The macro in the Autoconf macro repository
(ACX_PTHREAD) is not proving useful due to not working on common
platforms (e.g. Solaris).
