General

	Remove reliance on C's string functions and sprintf() so
	strings with NULs can be handled.

	A load of example programs are required as is a general
	tutorial document.

	Investigate use of autoconf for configuring and building.

regexp.c

	There are some broken bits in this version of Henry Spencer's
	regexp code. One of the tests fails and some users have mentioned
	problems with patterns that don't do what they expect. This
	needs looking at. For the moment the particular test has been
	commented out (search for XXX in tst-regexp.dat).

skt.c

	send() and recv() should allow flags to be specified.

	Non-blocking I/O support ?

syscall.c

	Need to split prototypes on a per-system basis to remove the
	maze of nested #ifdef's. This should be a high priority.

	Complete f_spawn() for Win32. Needs error checking/raising
	and potentially some mechanism for waiting for spawned things.

clib.c

	Error handling for file I/O functions. Currently getXXX() assume
	we've hit EOF and printf() silently fails.

doc

	Need better documentation for ,

		binary-@ operator
		spawn for Win32

	Need some tutorials.
