[ANN] mathx -- C99 math functions for Lua

[Luiz Henrique de Figueiredo <lhf@...>]

I've found and updated my C99 math library for Lua:
	http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/5.1/lmathx.tar.gz

This code extends the math library with the following functions and values:

acosh		exp2		ilogb		log1p		rint
asinh		expm1		infinity	log2		round
atanh		fdim		isfinite	logb		scalbn
cbrt		fma		isinf		nan		signbit
copysign	fpclassify	isnan		nearbyint	trunc
erf		gamma		isnormal	nextafter
erfc		hypot		lgamma		remainder

The binding is based on this page:
http://www.dinkumware.com/manuals/default.aspx?manual=compleat&page=math.html

The code does compile and run in Linux and Mac OS X 10.4. I haven't
tried it anywhere else. The test program does not do much.

All feedback welcome. Enjoy.
