Richard Earnshaw <rearnsha at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target| |arm-eabi --- Comment #2 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- The standard headers should only be defining bool if stdbool.h has been included. So this looks more like a build environment error than a bug in GCC.
