Are GCC and other compilers declaring that they support the GNU C and C++
languages by defining __GNUC__ really the only compilers with this
extension? Feature tests for particular features are generally better
than testing for whether the compiler in use is GCC. (Using configure
tests for things in ansidecl.h does require checking where in the gcc and
src repositories those things are used, to make sure that the relevant
configure tests are used everywhere necessary.)
(Actually, C++03 appears to support enum bit-fields - it's only for C that
they are a GNU extension - so can't we just enable them unconditionally
when building as C++?)
