--- Comment #10 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-06-13 11:36:50 UTC --- I agree in principle about the "c++config.h" (aka os_defines.h) header of the broken targets (which would be, I suppose, djgpp and mingw32) and considered using it earlier today, but at the moment it's included inside the guards of c++config itself (and has its own guards). What shall we do about that?
