Kurt Zeilenga 588a458d78 MSVC5 cleanup...
lber: ifdef'ed out lber_..set_nonblock() function because it used ioctl's.
  If it remains, it needs to be written to support various methods for
  setting non-blocking.  ioctls should probably be last choice.  configure
  could detect existance of fcntl(), ioctl(), etc.
bdb2:
  added .dsp/.dsw files and did some basic cleanup (still needs work).
