Nevermind. I've found a solution that I believe is quite good. For the
benefit of anyone else who may be grappling with this, here is the
relevant section of my configure.in:
child_type=unknown
AC_CHECK_HEADERS(sys/ipc.h, child_type=sysipc)
AC_CHECK_HEADERS(pthread.h, child_type=pthread)
AM_CONDITIONAL(ENABLE_PTHREADS, test "$child_type" = "pthread")
if test "$child_type" = "unknown"; then
AC_MSG_ERROR([could not find an acceptable multitasking library.])
fi
This should scale well, doesn't rely on undocumented features and even
looks pretty.
