documented naming scheme (unfortunately the documentation isn't in the tree as far as I can tell); no repocopy is required as there is no history to preserve. - replace simple and almost-correct implementation with slightly hackish but definitely correct implementation (tested on i386, alpha, sparc64) which requires pulling in fpmath.h and the MD _fpmath.h from libc. - try not to make a mess of the Makefile in the process. - enterprising minds are encouraged to implement more C99 long double functions.
