Questions about the CVS build process

[Tkil <tkil at scrye dot com>]

Hi there.  I am building from the CVS sources (as of about 2000-11-14
20:00 -0700), and I have a few questions:

1. Can a snapshot be converted into a CVS sandbox?  I ended up just
   doing a full cvs checkout, but at least one other large project
   (mozilla) recommends downloading the snapshot, unpacking it, then
   using cvs to grab only the deltas since then.  (They apparently
   simply package up the CVS subdirectories in the snapshot tar file,
   and it "just works."  I'm no CVS guru, so I'm probably missing
   something obvious).

2. Can the install prefix be changed after doing a bootstrap?  Or do I 
    have to do a full configure + bootstrap cycle again?

3. Is there a way that configure can detect that it's being run in the
   source directory (instead of a sibling "build" directory of some
   sort), and abort?  I didn't read the instructions closely enough
   the first time, and apparently I did enough damage to the sources
   that it was quite unhappy.  I ended up removing the first tree and
   doing another checkout from scratch, and it seemed much happier
   after that.

   (In case anyone cares, it died looking for "../install-sh" or
   similar.  I just blew away that portion of the build log, of
   course, otherwise I'd have the actual error for you...)

If these questions are answered in the docs, then I apologize for the
inconvenience, and a pointer would be appreciated.

Thanks,
Tony

p.s. Should I/we care about the fairly large number of these warnings?

     warning: integer constant is unsigned in ANSI C, signed with -traditional
     warning: comparison between signed and unsigned
