  etc/emacsclient.c in emacs v. 18.55 calls abort() if it can't get
the current working directory.  This is a bit extreme, since any
number of situations may cause this problem (and I don't think
anything of them are drastic enough to require an abort()).

  The following patch implements (for the bsd half of the program, at
least) behavior that is a bit better.  Note that I've tested this
under 4.3bsd, but I haven't tested it under 4.2 or 4.1 -- I don't know
if errno, sys_nerr or sys_errlist are defined in errno.h (or if they
even exist -- I'm pretty sure errno does, but I'm not sure about the
others) under 4.2 or 4.1.
