If you have the bucks (>$1k) you can get:

1). Phar Lap DOS EXTENDER, which allows running programs in 386 protected mode
    while still getting DOS function access (as well as being able to capture
    interrupts).  Virtual memory management is available at extra cost.

2). Either Microway's NDP C-386 compiler (tends to be UNIXish) or the Metaware
    High C 386 compiler (somewhat strange, but generates the best code).

If you don't have the bucks, your best bet is to find the bucks as dealing with
expanded memory is a real pain. You'll also loose about half the efficiency
of the chip running it as a brain-dead 8086.
