Thanks for your suggestion. Interestingly we thought recently about this 
solution, but found it quite 'hacky' (but better, as you say, than 
recompile Lua) as it is an internal fix on our side for something we 
believe should be fixed for everybody in Lua itself.

That is why I was pointing out that there is a problem in "require()", 
which has not been addressed until now. For what I saw in the previous 
posts of the mailing list, this issue has been ignored based on some 
false argumentation: according to the gcc documentation, it is a *fact* 
that the flag RTLD_GLOBAL should be used for C++ libraries (at least the 
ones which uses RTTI).

As the "require" function exists, it should work on all kind of 
libraries and the same on all platforms! It does work under Windows, but 
does not work under any platform using gcc.

Cheers,
Ronan.
