--- Comment #17 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> --- (In reply to Iain Sandoe from comment #16) > Hmm the patch for __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ has been > applied to 4.9 (AFAICT) Yes it has. > although not to 4.8 You're right. Provided that the patches are simple, maybe it's good enough to document them (as I have in the __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ patch for 4.8) and let distributors apply them.
