19    Description:
20    
21    Fixed IEEEReal.scan (and .fromString) so that if there is an overflow
22    in the exponent calculation we get INF or ZERO (depending on the mantissa
23    and the sign of the exponent).

32    goes wrong.

46    Tag: leunga-20040319-cygwin-nlffi
47    Description:
48    
49    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
50    of SML/NJ.  The problem is that
51    
52       lib = dlopen(NULL, ...)
53       f   = dlsym(lib, "malloc");
54    
55    does not work on Windows unless we explicitly export symbols
56    such as 'malloc' during linking.  We fixed this by explicitly
57    exporting the required symbols with the magic gcc incantation:
58    
59        -Wl,--export-all cygwin.def
60    
61    where cygwin.def is a file containing all the symbols that
62    we wish to export.
63    
64    I suspect this is a Windows problem and we'll have to
65    do the same (somehow with windows compilers) when
66    we build the native win32 version with the system
67    calls LoadLibrary/GetProcAddress.

73    Description:
74    
75    Fixed problem with IntInf.fmt (sign would show up on the right instead
76    of on the left for BIN, OCT, and HEX).

81    Tag: blume-20040304-symlinks
82    Description:
83    
84    Fixed problem with installer script (unix only) where bin/ml-yacc and
85    friends pointed (via symlinks) to absolute locations instead of just
86    .run-sml.  This was reported by Vesa A Norrman.

134    Tag: blume-20031104-move-libraries
135    Description:
136    
137    Eliminated the "dont_move_libraries" directive in config/targets.
138    (The mechanism was broken and could not be fixed easily.  Moreover,
139    there does not seem to be any reason not to move all libraries into
140    lib during installation.  I originally implemented this directive as a
141    backward-compatibility feature when I first introduced the new CM.
142    Now that things have been stable for a long time and going back to the
143    old CM is not an option, there is no reason to keep it around.)

192    Tag: blume-20030926-ppautoload
193    Description:
194    
195    I modified the read-eval-print loop so that the autoloader gets
196    invoked whenever the prettyprinter tries to look up a symbol that
197    is not currently defined in the toplevel environment but which
198    appears in CM's autoload registry.  As a result, we see far fewer of
199    those ?.Foo.Bar.xxx names in the prettyprinter's output.
200    
201    In addition to this I tried to clean up some pieces of the Basis
202    implementation (e.g., Socket, Word8Array) in order to prevent other
203    instances of these ?.Foo.Bar.xxx names from being printed.
204    
205    The mechanism that picks names for types still needs some work, though.
206    (Right now it seems that if there is a type A.t which is defined to
207    be B.u, but B is unavailable at toplevel, then A.t gets printed as
208    "?.B.u" although the perhaps more sensible solution would be to use
209    "A.t" in this case.  In other words, the prettyprinter should follow
210    a chain of DEFtycs not farther than there are corresponding toplevel
211    names in the current environment.)

216    Tag: blume-20030924-installer
217    Description:
218    
219    Another installer tweak:  All the ML code for the installer is now
220    compiled during CMB.make and put into a little library called
221    $smlnj/installer.cm.  The installation then simply invokes
222    
223       sml -m $smlnj/installer.cm
224    
225    and everything happens automagically.
226    
227    Win32:  ML code senses value of environment variable SMLNJ_HOME.
228    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
229            and BINDIR.
230    
231    The new scheme guarantees that the ML code responsible for the installation
232    is in sync with the APIs of the main system.  Also, the installer is
233    somewhat faster because the installer script is precompiled.

238    Tag: blume-20030924-synsock
239    Description:
240    
241    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
242    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
243    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
244    implementations of non-blocking operations from CML's Socket
245    structure.

250    Tag: blume-20030924-sockets
251    Description:
252    
253    1. Fixed SOCKET API and implementation to match Basis spec.
254       This required changing the internal representation of sockets to one
255       that remembers (for each socket file descriptor) whether it is currently
256       blocking or non-blocking.  This state is maintained lazily (i.e., a system
257       call is made only if the state actually needs to change).
258    
259    2. OS-specific details of sockets were moved into separate files, thus
260       making it possible to unify the bulk of the socket implementations
261       between Unix and Win32.
262    
263    3. CML's socket API changed accordingly.
264       (Note that we need to remove non-blocking functions from this API
265       since they are redundant in the case of CML!)
266    
267    4. CML's socket implementation now makes use of non-blocking functions
268       provided by Basis, thus removing all OS-dependent code from this part
269       of CML.
270    
271    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.
