I should probably have sent a heads up to this list, to announce this new setting, which installs clang as /usr/bin/cc, /usr/bin/c++ and /usr/bin/cpp, effectively making it the "default compiler". That said, I made a mistake in r232322, which introduced the setting, causing gcc not to be built at all if you had all default settings, except CC=clang, CXX=clang++ and CPP=clang-cpp. This caused no 'cc', 'c++' and 'cpp' executables to be installed under the temporary object tree. It should theoretically work, but some tools like lint still have 'cc' hardcoded, and thus they fail. I have worked around this in r232522. Please update to that revision, and try again. > In my case things developed even worse.
