Hello Paolo!
Building older GCC releases with clang tends to issue warnings. This
can be annoying especially when they originate from a header. While
backporting r242743 I noticed that the non-C++ cases of the changed
macro definitions in gcc/system.h are broken. Since GCC trunk is build
in C++ mode this is not an issue, but should be fixed nevertheless I
think.
Regards,
Gunther
