inline-math-1.7 (fwd)
I haven't taken a look it this yet, but would we want to replace the
mathematical functions mentioned below with these new routines? I
caught this, and I believe that it points out a flaw (minor) in GCC,
and improvements to the math functions.
Ideas, comments, flames?

Version 1.7 of inline-math has been uploaded to sunsite:
/pub/Linux/libs/inline-math-1.7.tar.gz.
Inline-math is a set of gcc inlined floating-point math routines
that can typically improve execution speed by 10%. These routines
avoid using the flawed algorithms for sinh, tanh, asinh, and atanh
found in libm (which produce incorrect results for small arguments).
The new version intefaces better with GCC to avoid producing code that
can overflow the register stack in complex routines. Specifically, exp(),
expm1(), and atan2() were rewritten. Inlined versions of pow(), ceil(),
floor(), and the math extensions log2() and pow2() were also added.
