The built-in functions nan, nanf, nanl, nans, nansf, nansl are not
part of C90; they should not be built in in C90 mode.  nans* are
not in C99 either.  Furthermore, the treatment of these as constant
expressions in some cases means they shouldn't be built in at all
with the names nan*, only with the __builtin_nan* names.  This accords
with the manual, which only documents them with those names and not as
nan*.

A patch is in testing; this PR is to record the issue as a regression
in 3.4 relative to 3.2.x and earlier.  (The same bug is in 3.3.3 but
would need a separate patch there as builtins.def has been reorganised
since then.)
