ANN: Lua Number patch, full revise

[Asko Kauppi <askok@...>]

The LNUM patch allows easy and wide configuration of Lua number  
types, with the use of simple compiler defines. It provides added  
integer accuracy (32- or 64-bit), enhances speed on non-FPU systems  
and allows use of complex numbers (C99 required).

The 3-Oct 2007 LNUM patch is a major revise, and will be the only  
maintained version from now on.

Changes include:
- better configuration system, using LNUM_FLOAT, LNUM_DOUBLE,  
LNUM_LDOUBLE, LNUM_INT32, LNUM_INT64, LNUM_COMPLEX (or a combination  
thereof)
- complex mode code fully revised, using C99 operations (shorter,  
simpler code)
- better automatic test suite (not part of the patch)

Limitations:
- Complex mode currently requires integer optimization (defining  
either LNUM_INT32 or LNUM_INT64)

Users are requested to update to using this patch instead of earlier  
ones. This is partly in order to get broad test reports, so please be  
careful and not for production builds, just yet. :)

The patch is available for Lua 5.1.2 only.
