To me this sounds like e.g. roundeven and fadd (and, generally, any new libm functions we add built-in functions for) *should* be included in the list like all the other libm functions, given that on many systems they can't be expanded inline for all arguments and so will generate UNDEFs (and some people might want to get them from a static library) - even if some systems' libm might in fact not have those functions. -- Joseph S.
