I find that __builtin_constant_p() works as expected, but
__has_builtin(constant_p) denies it !
Similarly __builtin_expect() and __builtin_types_compatible_p() !
Can I just assume these are all supported by all version of clang ?

I believe you need __has_builtin(__builtin_constant_p).

It works with gdb. More info:
g++ & gdb -- works, even without debuginfo for libstdc++
clang++ & gdb -- works
g++ & lldb -- works
clang++ & lldb -- fails
I now notice these warnings in lldb after installing the debug
