I'm sorry, but lua2c does not handle anonymoous functions and upvalues.
There's no way to create an anonymous function using the API: you need to create
a static C function first and then register it.

I;ll see if I can come up with a simple solution for this.
In any case, I do not see lua2c (yet) as a general tool: right now it excels
at code fragments, not complete Lua programs.

>what does the MOVE operation do

You seem to be running luac from 4.1 not from 4.0. lua2c only understands
the output of luac from 4.0 (but the generated code should work in 4.1).


For the body of your code, I get
/*
    return function (self, parms)
       self:log(%event, parms)
    end
*/
/* -------------------------------------------------------- */

 lua_pushXXX(L,self);
 lua_pushstring(L,"log");
 lua_gettable(L,-2);
 lua_insert(L,-2);
#error cannot handle PUSHUPVALUE
 lua_pushXXX(L,parms);
 lua_call(L,2,0);

/* -------------------------------------------------------- */

Perhaps it's a start.
