Hi When compiling libm under Linux/ia64 I get a bunch of warnings about implicit declarations of a bunch of math functions and a single warning about missing parantheses in ldbl-96/e_atan2l.c. It wasn't quite obvious if the prototypes for the missing functions should go in math.h or math_private.h so I stuck them in math_private.h but feel free to move them if I am wrong.
