	* Fix socket value mappings (tables were interchanged).

	* Unify all of the various patches required for iBCS2 into
	one file.

	* Eliminate test for bmap in binfmt_elf.c.

02 March 1994

	* Add socket value mappings. This meant a general move round
	  to tidy things up and group map functions/tables.
	  There is a new kernel patch in the Patches directory called
	  net.patch which gives us access to the sock_*sockopts
	  functions directly.


25 February 1994

	* Pedantic change to call maps so that IBCS_function contains
	  a void * instead of a function pointer - we cast it as
	  necessary later in emulate.c. The warning were annoying me.

	* Moved struct abi_sigaction from signal.c to abi4.h so it is
	  available for prototype declarations. Changed prototype for
	  abi_sigsuspend to correspond to implementation in signal.c.
	  -- Mike

	* Reversed out Eric's earlier signal patches and added new ones.
	  -- Mike

	* Updated trace code and trace control program to be useful.
	  Control of tracing individual functions is still not there
	  yet - perhaps another day.
	  Default trace mode is now none (i.e. only functions with
	  the trace flag set are traced). Use the trace program to
	  change the trace level.
	  -- Mike

	* File modes (open/fcntl flags) are different between Linux and
	  iBCS so we need to map between them. Open also requires this
	  so fcntl.c is now merged with open.c. Failure to set and reset
	  non-blocking mode was what was breaking Unipox.
	  -- Mike

	* Signal handling function changes to map to and from the Linux
	  signal set and sigaction flags correctly.
	  -- Eric


24 February 1994

	* Added code to the emulate() function to let us know when we
	  are about to process a signal on exit from the syscall.
	  -- Mike

	* Implemented proctl() as a no-op. It's not really relevent
	  under Linux.
	  -- Mike

	* Added argument count and type for eaccess()
	  -- Mike

	* Have emulate.c return -ENOSYS for unimplemented system calls
	  rather than zero.
	  -- Mike

	* Added Eric's patches to waitpid.

	* Created the ChangeLog!
