m4_pattern_forbid([^cr_])

dnl AC_AUTOCONF_VERSION was introduced in 2.62, so its definition works as

dnl a conditional on version >= 2.62.  Older versions did not call

dnl m4_pattern_allow from AC_DEFINE and friends.  To avoid lots of warnings we

dnl only forbid CAIRO_ if autoconf is recent enough.
