I'm embedding Lua in my application, and will only execute object code 
created from luac (no parser).  Memory space is very tight.
Two quick questions:
1)  In 5.0, I think I just didn't include lparser.c and that removed 
the parser (it's been a while).  How do I do that in 5.1?
2)  In trying to test out 5.1 in my application, I got a lockup.  I 
was doing a:
   if ( luaL_loadbuffer(L,B,1069,"'..Main..'") || lua_pcall(L,0,0,0) )
       fprintf(stderr,"%s\n",lua_tostring(L,-1));
   However, the buffer I was passing it was compiled with Lua 5.0.  
Did any opcodes change between 5.0 and 5.1?  I assumed the VM 
instructions were the same (bad assumption on my part?).  No big 
problem, just need to know.  I haven't compiled luac for 5.1w5 into 
this system yet.  I can do it, if needed.
TIA
