Bug ID: 63810 Summary: gcc sets incorrect macro for OS X deployment targets Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: driver Assignee: unassigned at gcc dot gnu.org Reporter: jeremyhu at macports dot org Even after the change for bug #61407, gcc is not setting up the deployment target macro correctly. gcc always sets the tiny version to 0 which is not always the case. For example: $ echo | clang-mp-3.5 -E -dM - -mmacosx-version-min=10.09.04 | grep __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ #define __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ 1094
