  My thanks to everyone who responded to my question on doing
I/O redirection for a child process without disturbing the
parent processes I/O under Microsoft C 5.0.

  Apparently the only way to do it is by using dup() to copy
stdin/stdout/stderr before starting the child process, and
dup2() to restore them afterwards.

  The only drawback is that Microsoft C already reserves 5 fildes.
If I dup() three, that only leaves 12 for the child process...
