You'd have to replace the sqrtf with __builtin_sqrtf. The
non-__builtin_-prefixed names are not defined in C++, because
-fbuiltins is disabled and can't be re-enabled in C++. From
cp/decl.c:
/* In C++, we never create builtin functions whose name does not
begin with `__'. Users should be using headers to get prototypes
in C++. It would be nice if we could warn when `-fbuiltin' is
used explicitly, but we do not have that information. */
flag_no_builtin = 1;
