True. The programmer still has to write to the standard. It is all too
easy to cross the line into nonconforming code, and sometimes it is
unavoidable.

GNV makes it unavoidable, because it is nonstandard. Some of the
interfaces have different semantics than the standard, when they exist
at all.

So you end up writing conditional code around the semantic variations,
and using something like "configure" to determine at compile time
which code to use.
