You mean in the libc? It's possible because as you can see the autoconf test handles all the C99 mathematical functions together and if only one is missing the check fails. Now, really, I don't think we want to go fine grained to the level of the single function, but if for example we figure out that a number of targets has available the entire subset of functions required for <random> and <ext/random> we could separate those. My point is that we should try to find patterns, like the long double functions are causing troubles and we can separate those. As I said, for those features - isn't just about math - I would rather not fragment everything down to single function, if possible. > Testing suggestion. Great, if it works, let's go with that for now. Then, longer term, if you have ideas about the above, please also feel free to send a message to the library mailing list.
