It's a problem with platform-specific inclusions: xterm.h includes dispextern.h, 
but eval.c and lread.c don't include xterm.h on MS-Windows. I attempted to 
detect this sort of thing by hand without actually building on MS-Windows, but 
it's an easy thing to get wrong. Revised patch attached. Quite possibly there 
will be similar issues on other platforms, but they should be easy to fix once 
encountered.
