------- Comment #7 from rguenth at gcc dot gnu dot org 2007-03-20 11:04 ------- I agree it's surprising to get user-visible effects with the TARGET_C99_FUNCTIONS difference between the frontends, but they are (supposed to) providing C99 runtime completion by their runtime libraries. And they rely on full C99 support.
