Re: compiling LUA for uClinux

[Asko Kauppi <asko.kauppi@...>]

The patch is not publicly available anywhere, yet. I am using the 
INT32_PATCH internally in LuaX future versions, but without this 
mention, who would notice?  Anyhow, it seems stable to use.

There's actually a couple of more patches in there, each should be 
independently on/off settable using following defines:

	USE_FLOAT	my config for making Lua use float's (affects too many 
places, still)

	INT32_PATCH	the thing i mentioned, transparent int storage & 
optimization
				can be used either with 'double' or 'float' numbers

	ENUM_PATCH	an experimental thing for enumarated types / bitwise ops
				(similar to int32, but they are actually very different in usage.
				 this is not transparent, but an extension)

	USE_FIXED	interesting --very experimental-- patch to use fixed-point 
numbers
				instead of float (preferably, in combination with int32 patch).
				This would allow transparent, almost normal Lua behaviour, _without_
				using floats (but in the API interface).  alternative for total 
int-only.

I'll be glad to send the patched src/ dir contents to anyone wanting it 
(did already to you). I am not intending to package it into a dedicated 
patch format.
