[cfe-commits] [patch] Fix -fno-exceptions for c++

[Rafael Espindola]

Currently __EXCEPTIONS=1 is always defined when compiling c++. The
attached patch fixes it:

clang -E -fno-exceptions test.c        disabled
clang -E -fexceptions test.c             enabled
clang -E test.c                               disabled
clang -E -fno-exceptions test.cc      disabled
clang -E -fexceptions test.cc           enabled
clang -E test.cc                             enabled

But it looks silly :-)

Is there a way in clang-cc to test that an option was not given (as
opposed to having the default value)?

Cheers,
