dnl @synopsis LIBOPTS_CHECK
dnl
dnl Time-stamp: "2012-02-25 12:54:32 bkorb"
dnl
dnl If autoopts-config works, add the linking information to LIBS.
dnl Otherwise, add ``libopts-${ao_rev}'' to SUBDIRS and run all
dnl the config tests that the library needs. Invoke the
dnl "INVOKE_LIBOPTS_MACROS" macro iff we are building libopts.
