As we discussed, it has fallen into disuse. Its main purpose was to
pave the way for the .net backend and later for the java and csharp grades.
Now that the .net backend is ancient history and the java and csharp grades
are established, that purpose is gone, and for every other purpose,
hlc is better because it is simpler and faster.

Fix linking error for hlc.par.gc grade on Darwin. The problem was that the
"-undefined suppress" option is not allowed with two level namespaces.
The solution is to use "-undefined dynamic_lookup" instead.
However this means the MACOSX_DEPLOYMENT_TARGET environment variable must be
set to 10.3 since this feature will not work on Mac OS < 10.3. To allow
hlc.gc.par to be built on Mac 10.3, but targetted for Mac OS 10.0 - 10.2 add
a configuration option to force the use of flat namespaces (the
"-undefined suppress" option may be used with flat namespaces).

Add the option `--file' to mmake. This allows the user
to specify the name of the file that mmake uses as the Mmakefile.
This can be useful when porting programs between systems
and experimenting with different configurations, particularly
when the programs are not under the control of autoconf.
The option `--file' may be abbreviated to `-f'. If a file
is specified via `--file' then it will be used in preference to
any file in the current directory named Mmakefile or Mmake.
Unlike GNU make using multiple instances of `--file' will
not cause mmake to jointly use all of the specified files.
Instead it will use the last one specified and ignore the
others.

Allow reconfiguration of existing installations, for example
to use a different C compiler. The reconfiguration works
by making a new copy of the scripts and mercury_conf.h,
and storing them in a partial installation directory tree
which uses the libraries and executables from the existing
installation.
Use this method to configure binary distributions, rather
than using a cut down version of the configuration script,
to avoid code duplication and to handle the case where the
C compiler in use on the installation machine is different
than that used to build the binary distribution.
This is more robust than the previous method of using a different
C compiler, which was to set the MERCURY_C_COMPILER variable and
hope the different C compilers were compatible enough.

Allow alternative locations for the standard library files
to be specified using options to the various Mercury scripts
rather than environment variables. This change is necessary
to allow the compiler to be compiled using `mmc --make', because
`mmc --make' does not support the environment variables.
All of the Mercury scripts now accept an option
`--mercury-standard-library-directory' to specify the installed
library to use, or `--no-mercury-standard-library-directory' to
disable the use of the installed library. The location
of the alternate files to use can then be specified
using ordinary options to the scripts.
There is a new environment variable MERCURY_STDLIB_DIR, which has
the same effect as the `--mercury-standard-library-directory' option.

(to do this merge... 100s of hours on the HAL branch
itself by myself and Warwick Harvey though).
Merge the changes from the HAL branch onto the main branch. With the recent
changes made to the HAL implementation, this means adding just one grade,
`.rt' or --reserve-tag, which reserves one tag (zero) in each type for
use by HAL's Herbrand constraint solver. This disables no-tag types and
enumerations.
This grade will now bootstrap, and passes all tests, except for a few failing
cases in the debugger and tabling directories.

Add predicates `type_util__constructors_are_dummy_argument_type' and
`type_constructors_are_type_info' for use when allocating tags to
ensure that type infos and dummy types (io__state/0 and store__store/1)
are still treated as no-tag types in .rt grades.
library/sparse_bitset.m:
When allocating a sparse bitset element, use tag `1' if we are in a
.rt grade.
runtime/mercury_tags.h:
Define a macro `MR_UNIV_TAG' which is `1' is we in a .rt grade and
`0' otherwise. (Now that univ is a user defined type, it is a also

Also make the definitions of MR_RAW_TAG_NIL and MR_RAW_TAG_CONS take the
.rt grade into account.
runtime/mercury_type_info.h:

because compiler/static_term.m assumes that the generated code uses
the same data representation as the compiler itself. This should be
fixed, although it is not critical; the declarative debugger won't
work with trailing as is, and the .rt grade is only ever used in
conjunction with trailing (.tr) at this stage.

Split the automatically generated `.dep' file into two files. The new `.dv'
file contains all the variable definitions which used to be in the `.dep'
file, which now contains just the rules. With mmake including the `.dv'
files before the user's Mmakefile and the `.dep' files after, this allows
user-defined Mmakefiles to refer to the automatically-generated variables
and automatically-generated rules to refer to variables defined in the
user's Mmakefile. This was possible before to a limited extent, but in
particular dependency lists for automatically-generated rules could not
refer to user-defined variables.
Also introduced `C2INITARGS' as part of an illustration of how this change
is useful (though probably this should be a separate change). `C2INITARGS'
should be used to specify extra files to be passed to `c2init', rather than
the currently-used `C2INITFLAGS' (which should only be used for option
flags). The `_init.c' target should depend on these extra arguments, but it
was not possible to do this automatically prior to this change (at least,
not if one wanted to support per-program specification of `C2INITARGS').

Finish off the centralization of the file name handling code, and

Also add negative versions of the various options

scripts/Mmake.rules:
Add code to handle generating intermediate file names
in subdirectories. If MMAKE_USE_SUBDIRS=yes, we add
`--use-subdirs' to MCFLAGS, and most of the pattern rules
are changed to use subdirectories.
Note that getting this to work required a bit of a hack:
due to what seem to be bugs in GNU Make, `mmake depend'
needs to do `mmc --make-short-interface *.m' to get things
started. But once the int3s are there, the dependencies
seem to work OK.

scripts/mmake.in:
Check for `Mmakefile' as an alternative to `Mmake'.
(This change is so I can rename scripts/Mmake as Mmakefile
to avoid a conflict with scripts/mmake on systems with
case-insensitive file systems, e.g. Windows 95.)

Ensure that mmake does not attempt to remake the `.c' file if it is up-to-date.
(This change should hopefully fix a problem with the source distribution not
being able to bootstrap itself.)
Also a couple of minor tidy-ups.
scripts/mmake.in:
Export new variable MMAKE_MAKE_CMD, for use by Mmake.rules.
scripts/Mmake.rules:
In the rule for `.m' -> `.o', use a recursive invocatino of
make (via the MMAKE_MAKE_CMD variable) to build the `.c' file,
rather than unconditionally invoking `$(MCG)'.
scripts/.cvsignore:
Add Mmake.vars, since it is now automatically-generated.
scripts/ml.in:
Some stylistic changes: make sure that autoconf @var@ variables occur
only in assignments to shell variables at the start of the script,
not scattered throughout the body of the script.
scripts/*.in:
Replace all uses of
... "$@" ...
with
case $# in
0) ... ...
*) ... "$@" ...
esac
since on ULTRIX and OSF, "$@" does the wrong thing if $# is 0.
