Only the users of nonconforming compilers/platforms will need to use the
macro. Nothing is uglified.

Deciding between "works now" and "is the right thing" is difficult, but we
need to take into account that names we choose may well last for five-ten
years or more, long after the specific nonconformances are addressed by the
vendors.
