The cegcc build is already full of kludges, so one more wouldn't hurt. Danny, any objections?
Hi again. I've committed the attached patch to libstdc++/Makefile instead, using the same idea. Could you give it a try? I've tested it by doing this: MAKEFLAGS="-j 2" ./build-cegcc.sh . build-cegcc /opt/cegcc/ libstdc++ and this at the libstdc++ dir: make -j 2 Without the patch, I would see race problems; with the patch, no problems. Cheers, Pedro Alves
