Iain Sandoe <iains at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mrs at gcc dot gnu.org --- Comment #2 from Iain Sandoe <iains at gcc dot gnu.org> 2010-12-14 21:45:13 UTC --- it's all fall-out from the different assumed sizes of Bool (see also 46902). I think (subject to Mike's agreement) that, since Darwin's <stdbool.h> does not set bool to int for GCC > 3 ... that we should default to one byte bools on PPC darwin (there is no effect on x86).
