Changes in callproc.c and term.c

Dan, I have a comment about this change committed today:

    2009-07-03  Dan Nicolaescu  <dann <at> ics.uci.edu>

	    * callproc.c (child_setup): Use #else instead of a separate #ifdef.

This change is perfectly okay syntactically and semantically, of
course.  What bothers me is that it made two unrelated code snippets
look as if they do similar or related things on two different
platforms, because now they are in two sibling branches of the same
#ifdef.

However, this is a matter of style and personal preferences, so I'll
let Stefan and Yidong decide.
