Well, not really problems - just lack of experience on my side... ;-)

`make-executable-byte-vector' uses mprotect() internally (to give the
allocated memory executable permissions), and I'm not sure whether it is 
fully portable.

(If it is, will someone please tell me?)

Normally the byte-vector returned my `make-executable-byte-vector'
should not be executable on a normal UNIXish system. So unless they are 
(which I doubt), change line 48 of lolevel.scm by removing the 
`defined(__i386__)' and rebuild chicken.
