GCC would be permitted to expose these and still comply to standards. Doing so would make things so much easier for operating system implementors, like us. Clang does get it right, in my opinion. We should just extend to define _Static_assert() when using GCC in C++ mode (if we're not doing so already). -- Ed Schouten Nuxi, 's-Hertogenbosch, the Netherlands KvK-nr.: 62051717
