32-bit embedded

[Enrico Colombini <erix@...>]

Is there any documentation, however sketchy, summing up how to 
configure/patch Lua for a (32-bit) embedded system with no fp coprocessor?

I know about http://www.wra1th.plus.com/lua/zip/Luasrc.zip and "Go Long 
Lua!"

but I'd really like to have full knowledge and control of the 
customization process (I think I know some of the steps, but probably 
not all).
