This is harmless. The optimizer found this type specifier somewhere in the
code, but ECL currently does not handle VALUES type declarations in the
compiler. That's all.

It seems like I'm not able to access the CLX functions even though the code

I am not sure what you mean by "not able to access the CLX functions". It
seems that your code was indeed able to call XLIB's functions. What is
shown above is a protocol error, am I wrong? As Matthew explained, it may
be due to CLX, but it might also be due to ECL corrupting the communication
(unlikely but possible). I will try with some other machine myself.
