Here are some patches to make bash 1.02 work on 386/ix (SVR3.2).

The significant problems were:

-- it dumps core on EOF; this happens on a Sun 4/SunOS 4 as well

-- when a child process that catches interrupts gets an interrupt,
   bash also gets an interrupt and does a throw_to_top_level() with
   the result that the child process and bash end up reading 
   simultaneously from the terminal.

There were also a couple of minor glitches in the Makefiles: System V
make doesn't understand `%' in rules, and there's no ranlib.
