This code is still not in and is an increasingly serious problem for a lot of software. Two weeks from today, I will commit a patch that just calls the double versions of these for all of the long double functions. If you have a better implementation of any of them, please commit it before then. Style nits can be worked out later. Small bugs in corner cases can also be fixed later: it is far worse for us to have no implementation of these than to have a slightly buggy one, because it just drives people to use platforms that have very buggy versions of them instead of FreeBSD. > > David Unfortunately, life gets in the way of hacking on FreeBSD. However, it so happens that I'll be sending a patch to das@ in early June with an expl() update and an implementation for expm1l(). -- Steve
