Exactly that does not work, because issubnormal is a simple macro.
Only if before the implementation
#undef issubnormal
is made before implementation: https://godbolt.org/z/z3PG3hYev
That is incorrect.
* I have no idea what happens if math.h is already included somewhere and I
subsequently undefine issubnormal.
* It is not my job to program around any (compiler-specific) problems. The
compiler has to do it right or it doesn't support it at all.
Therefore issubnormal must be provided as a "real" function or via builtin.
