Two small additions/fixes:

- In a static shell, trying to load an unknown module should produce a 
  error message.
- bltinmods.list should contain #ifdef-DYNAMICs for the sake of static 
  shells (so that the autoload stuff for not linked-in modules isn't
  added by them).

The zshxmods.h stuff (the #ifdef stuff in init.c) looks ok, btw. But
it looks like shooting sparrows with cannons (is this a proverb in
English, too?). All the mess could be replaced with just the variable
definitions and a bit of setup code that just look if the zle module
is available (by looking if the bindkey builtin is made autoloaded
from a module named zle or something). Or we just make one of the
scripts look out for the zle module on the fly. Hm.

Bye
 Sven
