Folks, Parallel builds contain a race due to a missing dependency between gengtype-lex.o and $(BCONFIG_H).
This was introduced by the commit: http://gcc.gnu.org/ml/gcc-patches/2010-11/msg00926.html .. which injects an include of bconfig.h into the top of gengtype-lex.c but does not make both of the objects built from that file dependent on bconfig.h There is a simple fix, below, but I'm concerned that this is just papering over the cracks, is it really correct that both the build and host machine variants include the same config file?
