Abdulaziz Ghuloum c8111df150 * 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.

Abdulaziz Ghuloum 13e8f76f13 * intermediate step:
gc has tcbucket_size=16
  compile allocates tcbucket_size=24

Abdulaziz Ghuloum 872a5e2e9e * Added even? and odd? primitives. 2007-01-13 22:32:54 -05:00
Abdulaziz Ghuloum 212224b4cf * 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.
