* bug in collector causing dirty bits for code objects with younger reloc
...
vectors to be unset incorrectly. The bug was in using || instead
of | when computing the dirty pattern.

(automatically).

* fixed bug in handling tcbuckets.
...
Summary of the bug:
if ik_alloc is called during gc, and if it causes a heap
overflow, then the pages are deallocated before returning to
scheme.

* Added the primitive (environ):
...
returns an alist of (string x string) as obtained from the
system environ.
* Added the primitive env:
(env "key") retrieves the env value associated with key
(env "key" "val") sets the env value assocuated with key to val
(env "key" "val" overwrite?) same as above but it does not
overwrite an existing value of overwrite? is #f.
