ACL crashes on compilation of input.lisp

[Robert P. Goldman]

When trying to asdf-compile CLX on ACL 81 (linux) I get an error as follows:

 attempt to call `XLIB::EXTENSION-EVENT-KEY-P' which is an undefined
function.

Seems like this is being called at compile time by ACL, but not by SBCL. I don't claim to understand why.

I can fix this with two changes:

1. use eval-when to force XLIB::EXTENSION-EVENT-KEY-P to be defined at compile-time and

2. push the definition of the variable *extensions* upstream so that its value is available to XLIB::EXTENSION-EVENT-KEY-P at compile time.

I will try to attach a patch...
