[Chicken-users] CVS update

[felix]

- added `C_post_gc_hook'
- manual: clarified blocking behaviour of I/O from ports returned by `process' 
[Thanks to Tim Reid]
- extended range of character codes from 16 to 21 bit
- declarations are also registered in files loaded at compile-time
- chicken-setup: added `-dont-ask' option

Note: eggs can now safely override standard procedures by loading a file
with the required declarations ("(declare (not standard-binding ...))")
at compile time. I have changed the complex egg accordingly, to provide
an example.


cheers,
felix
