That depends on what you mean by "nil".  There's the symbol 'nil,
which has no special properties in Scheme.  There's #f (SCM_BOOL_F),
which is the Scheme-level false value.  And there's '() (SCM_EOL),
which is the empty list.

Strange.  SCM_EOL should be different from SCM_BOOL_F.  How exactly
did you observe this?
