"4.2.8 __has_c_attribute
The special operator __has_c_attribute (operand) may be used in ‘#if’ and 
‘#elif’ expressions in C code to test whether the attribute referenced by its 
operand is recognized by GCC in attributes using the ‘[[]]’ syntax."

How about HAVE_C23_ATTRIBUTE_CHECK, HAVE_C2X_ATTRIBUTE_CHECK, or something 
similarly more meaningful and less confusing?
