It's the most common one but pretty sure it's not the only one --- and,
supporting conditional compilation may involve only a tiny subset of cpp in
the user's code, but a fair bit more in terms of what cabal-install has to
generate for those triplet macros to exist for user code to use. There are
ANSI features we don't need (assertions, token splicing) but everything
else probably gets used one way or another.
