	* README: updated.

	* Makefile: made it slightly clearer what's going on, and added an
	`install' target.

	* low.c: fixed some glibc-related problems (sa_mask zeroed
	with `=0', ioperm() not in unistd.h any more, mmap() using
	void * for first arg rather than caddr_t). Still gives a
	warning about usleep() not having a prototype - might be due
	to _POSIX_SOURCE definition in cpmemu.h, but it doesn't worth
	the risk of possibly breaking things just to avoid a warning.
	:-)

	* Removed the `-N' from the Makefile. (The program doesn't
	actually need it, as far as I can tell, and using `-N' seems (for
	ELF) to require linking statically.)

	* Made COPYRIGHT.GNU a full copy of the usual GNU GPL `COPYING'
	file.

	* Added Michael's copyright banner to a file I noticed he'd
	omitted it from, `low.c'.

	* bios.c: fixed DIR problem, which I think was related to POSIX
	semantics for struct dirent in libc5/6 (i.e. ELF) which didn't
	exist in libc4 (i.e. a.out).

	* bios.c: the compute-file-size and set-random-record BDOS
	functions were *completely* broken. (These weren't new problems,
	but meant some useful things weren't usable - pmarc, for example.)

	* bios.c: fixed get/set user code BDOS functions. (Though it's
	debatable whether this is of any real use of not.)

	* bios.c: corrected assumption that fstat() returns 0 on failure -
	it returns 0 on *success*, and -1 on failure. This didn't actually
	cause any problems in practice as he'd opened the file just
	before, but I fixed it all the same.

	* Started this change log.
