Re: [ANN] Lua 5.2.0 (rc2) now available

Hello Roberto!

Your fix resolves the low memory condition.

I would have tested on monday with a device with more memory, but of 
course it is
practical to have a test for the smaller devices too.

I had to comment out pm.lua and  coroutine.lua, because with them 
lua.exe encounters
"a serious error and must shut down".

With files.lua I have to review several asserts.

- os.getenv()    - environment variables are not supported in Windows CE
- os.setlocale() - have to revisit my implementation
- os.rename()    - guess: problem with the fact that Windows CE does not 
have the
                   notion of a current working directory

For everything else I get a running time of about five Minutes:

- - -
\> datetime & \psm\apps\lua.exe -e"_U=true" \psm\apps\lua\all.lua & datetime
2011-11-27 Sun 21:21:32 668
current path:
[...]
total time: 299.64

.>>> closing state <<<

2011-11-27 Sun 21:26:32
----

Please note, that I think that the remaining problems are caused by 
Windows CE and/or
bugs in my port.

Can you give me a hint, how to quickly narrow down the specific location 
where the
respective problem arises in the test file and how to extract a small 
test case.
But don't trouble yourself too much, I'll figure it out myself also with 
some time.

Best Regards,

    Jorge-León
