To compile wattcp with djgpp requires a lot of changes. There is some
assembly code that needs to be rewritten (in C), and the low level
packet interface has to be changed to the 1.1 style. I once wrote a very
simple bsd-like wrapper on top of wattcp, but a real socket interface is
not possible.

An other sollution is to use Peter Tattems ?? tcpdrv. It's a TSR on top
of a packet driver. It offers almost the same interface as wattcp, but
it lakes e.g. a resolver interface. The missing code can be taken from
the wattcp librairy.

Last week I started to write a djgpp interface for the tcpdrv, but I
haven't got very far. If any one is interested in working on it
together, let me know. I think I would be a greatly simplify porting
unix code.
