[ANN] updated lqd, high-precision mathematical library for Lua

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

I've updated lqd, a high-precision mathematical library for Lua
providing about 64 decimal digits. It is based on qd:
        http://crd.lbl.gov/~dhbailey/mpdist/

lqd is available at
        http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/#lqd

Checksum and other data available at
       http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/release.txt

This release is self-contained: it contains the required qd source
files. It also sports a simplified Makefile with targets for macosx
and linux with -fPIC (which some people will appreciate!). I plan to
update my other libraries to use the same scheme.

Like all my code, lqd is in the public domain.
Enjoy. All feedback welcome.
