Ok. I thought that step was a trivial one.
Now a related question. How can a plugin know that cc1 was compiled with C++ or just with
plain C? I don't really know (we do have GCCPLUGIN_VERSION, but should a plugin use
ENABLE_BUILD_WITH_CXX)?
And I don't understand why the GCC 4.7 changes don't advertise loudly on
http://gcc.gnu.org/gcc-4.7/changes.html that the C language is obsolete as the language
in which GCC is coded, and that next release will *need* to be compiled with C++? Or is
something that tells it somewhere, in strong enough words or typography that nobody could
skip it? (I am not sure that a casual user, brave enough to compile GCC 4.7 from source,
did notice that C++ would be soon mandatory to compile GCC).
Cheers.
