Description Richard Biener 2010-06-06 11:50:34 UTC 
Without a C++ host compiler (AC_PROG_CXX fails) bootsrap with --enbale-build-with-cxx fails like

config.status: creating nm
config.status: creating Makefile
config.status: creating gccbug
config.status: creating ada/gcc-interface/Makefile
config.status: creating ada/Makefile
config.status: creating auto-host.h
config.status: executing default commands
make[2]: Leaving directory `/home/abuild/rguenther/obj'
make[1]: *** [stage1-bubble] Error 2
make[1]: Leaving directory `/home/abuild/rguenther/obj'
make: *** [all] Error 2

instead of complaining for the lack of a C++ host compiler.
