A small update about the non-compiling sword25 engine which currently  
blocks buildbot builds of the WinCE port:
There are some other functions used in the lua code which don't exist  
on WinCE; maybe some (all?) of them should be also added to common/ 
forbidden.h, but before doing this on my own, I'd like to know if you  
agree with the following list:

tmpfile (liolib.cpp:171)
getenv (loadlib.cpp:415 & loslib.cpp:49)
system (loslib.cpp:22)
clock (loslib.cpp:55)
strcoll (lvm.cpp:205)
