In the spirit of the recent patches for bool and C23, here's a proposed pair of patches for C23's new keyword static_assert. This uses a similar approach, in that the existing assert-h module, which already provides an <assert.h> that supplies a static_assert macro, is modified to provide something like C23 static_assert even if you don't include <assert.h>. This patchset does differ from the bool patchset in that we can't assume the system <assert.h> supplies a static_assert macro since Gnulib doesn't assume C11.
I haven't installed these into Gnulib. Comments welcome.
