Since the common config/mh-darwin file doesn't exist on gcc-4_5-branch, the
following patch
creates a config/mh-x86-darwin to allow r175089 and r175108 to be effectively
backported. This
change is worthwhile to provide darwin11 users access to dragonegg (since
dragonegg doesn't
build on gcc 4.6.x yet). Bootstrap and regression tested on
x86_64-apple-darwin11. Okay
for gcc-4_5-branch?
