21		1. Added openVector, nullRd, and nullWr to PRIM_IO.
22		2. Improved .bat files (for Win32 port) to make things work under Win95.

45		Tag: blume-20030926-ppautoload
46		Description:
47
48		I modified the read-eval-print loop so that the autoloader gets
49		invoked whenever the prettyprinter tries to look up a symbol that
50		is not currently defined in the toplevel environment but which
51		appears in CM's autoload registry.  As a result, we see far fewer of
52		those ?.Foo.Bar.xxx names in the prettyprinter's output.
53
54		In addition to this I tried to clean up some pieces of the Basis
55		implementation (e.g., Socket, Word8Array) in order to prevent other
56		instances of these ?.Foo.Bar.xxx names from being printed.
57
58		The mechanism that picks names for types still needs some work, though.
59		(Right now it seems that if there is a type A.t which is defined to
60		be B.u, but B is unavailable at toplevel, then A.t gets printed as
61		"?.B.u" although the perhaps more sensible solution would be to use
62		"A.t" in this case.  In other words, the prettyprinter should follow
63		a chain of DEFtycs not farther than there are corresponding toplevel
64		names in the current environment.)

69		Tag: blume-20030924-installer
70		Description:
71
72		Another installer tweak:  All the ML code for the installer is now
73		compiled during CMB.make and put into a little library called
74		$smlnj/installer.cm.  The installation then simply invokes
75
76		sml -m $smlnj/installer.cm
77
78		and everything happens automagically.
79
80		Win32:  ML code senses value of environment variable SMLNJ_HOME.
81		Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
82		and BINDIR.
83
84		The new scheme guarantees that the ML code responsible for the installation
85		is in sync with the APIs of the main system.  Also, the installer is
86		somewhat faster because the installer script is precompiled.

91		Tag: blume-20030924-synsock
92		Description:
93
94		Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
95		but excludes all non-blocking operations.  Defined SOCKET (in Basis)
96		and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
97		implementations of non-blocking operations from CML's Socket
98		structure.

103		Tag: blume-20030924-sockets
104		Description:
105
106		1. Fixed SOCKET API and implementation to match Basis spec.
107		This required changing the internal representation of sockets to one
108		that remembers (for each socket file descriptor) whether it is currently
109		blocking or non-blocking.  This state is maintained lazily (i.e., a system
110		call is made only if the state actually needs to change).
111
112		2. OS-specific details of sockets were moved into separate files, thus
113		making it possible to unify the bulk of the socket implementations
114		between Unix and Win32.
115
116		3. CML's socket API changed accordingly.
117		(Note that we need to remove non-blocking functions from this API
118		since they are redundant in the case of CML!)
119
120		4. CML's socket implementation now makes use of non-blocking functions
121		provided by Basis, thus removing all OS-dependent code from this part
122		of CML.
123
124		5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

131
132		Made a new interim version and bootfiles for developer's bootstrapping
133		convenience.
134
135		110.43.2 -- NEW BOOTFILES

140		Tag: blume-20030919-cmdir
141		Description:
142
143		1. new-install.sh -> install.sh
144		2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
145		3. tweaked installer so that another name instead of .cm can be chosen
146		at install time (by setting the CM_DIR_ARC environment variable
147		during installation); once installation is complete, the name is
148		fixed

165		Description:
166
167		1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
168		this seems to be controversial at the moment) and used those in
169		Posix.ProcEnv.times.
170
171		2. Added Time.{from,to}Nanoseconds to Time.
172
173		3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
174		For example, fromLargeInt never needs to look at more than 3 "big
175		digits" to get its 53 bits of precision.
