LuaJIT 2.0 and renaming standard libraries

[Thomas Bernard <thomas.bernard@...>]

Hi,
I just upgraded from LuaJIT 1.6 to LuaJIT 2.0 and found that the 
mechanism to rename internal libs doesn't work anymore. I need that to 
avoid symbol name collisions with some internal functions I have which I 
would prefer to leave untouched.

I've managed to achieve what I wanted by patching the individual source 
files of the distribution but it might me usefull to renable the 
renaming mechanism.

Great work by the way !

Thomas Bernard
