TODO

* Make it possible to append to wattcp.dbg files.

* Store PKTDRVR handle value and address of DOS-memory Rx buffers in
  master environment and optionally release PKTDRVR handle at next
  startup (in case program exited abnormally).

* Support and test for Pmode/DJ

* Support and test for Zurenava (ZRDX)

* Support for Pharlap extenders with Watcom.

* Support "non-zero base" version of DOS4GW Pro extender (using Watcom).

* DJ_BUG in pcpkt.c: Check if highword of ESP set in the RMCB wrapper is 0
  (assuming it's a 16bit segment).
  Check if reserved field in __dpmi_regs (between EBP and EBX) changes
  in callback.

* Notes on gcc code-generation:
	`-mcpu=CPU-TYPE'
	Tune to CPU-TYPE everything applicable about the generated code,
	except for the ABI and the set of available instructions.
	...
	While picking a specific CPU-TYPE will schedule things
	appropriately for that particular chip, the compiler will not
	generate any code that does not run on the i386 without the
	`-march=CPU-TYPE' option being used.

	So -mcpu is a tuning option that does not restrict the
	instruction set, while -march is a restrictive option, and
	-march=x also implies -mcpu=x.


* Fix IPv4 reassembly; handle frags sent with highest offset first.
  And move the reassembly up in the protocol chain (to _ip_Handler).

* Better TCP reassembly. Simulate packet-drop in pcpkt2.c.

* Support djgpp near-pointers to the receive buffers.

* USE_FAST_PKT for all targets. Prevents fixup error in large model and
  with Blinker (which crashes on 16-bit segment in asmpkt4.asm).

* Write a djgpp stub-edit tool that puts build-time and version in the
  COFF optional header (after the file-header).

* Support default gateway = my_ip and ARP for everything.

* Port Sandia Labs' XTP real-time protocol to Watt-32.  DON'T THINK SO.

* Add support for Win-9x/ME and Win-CE (Dell Axim, ARM processors).
