I can see how you might make this mistake, based on the documentation
in the source of AG_PATH_AUTOOPTS:

dnl AG_PATH_AUTOOPTS([MIN-VERSION, [ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])

The [] above are not intended to be correct m4 quoting, but rather
simply show that all the arguments are optional.  Try:

AG_PATH_AUTOOPTS([5.12], [], [AC_MSG_ERROR([Autoopts not found])])

or possibly

AG_PATH_AUTOOPTS([5.12], [], AC_MSG_ERROR([Autoopts not found]))

My hunch is the first one will work, my head thinks the second one
makes more sense.  So much for understanding m4 :)
