I fear the macros are going to be needed anyhow to support pre-C11 
compilers.

Qt itself can stop using them in C++ code (switching over 
static_assert). And I'd say that C++ mode we can assume static_assert 
presence everywhere, although the compiler detection will still be 
needed for C.

Whether the macros should be documented or not: I keep asking, are they 
supposed to be public API? My answer is more towards a "no", but given 
we're keeping them around anyhow for C, I'd say to keep them working 
also for C++.

Maybe we can use some trick to raise a warning for C++ code, but the 
maintenance burden for the C++ version is going to be 0.

A data point: KDE has (only) ~30 hits of Q_STATIC_ASSERT.
