These names were all introduced before the C99 standard made
"restrict" official, so I don't expect many more aliases to crop up.

We could split things up in a backward-compatible way, by having
config.h include (or bodily incorporate) a new file "config-have.h",
which defines only the HAVE_* symbols.  Then people who want the
newer, cleaner semantics could include "config-have.h".
