Filter out warning message from gcc 4.x which are emitted when compiling
low-level C code using assembler labels, at least until a better fix is
available.

util/mfiltercc.c:
Add a new program, mfiltercc.

Filter compiler output with mfiltercc if using assembler labels.
scripts/mgnuc.in:
Filter compiler output with mfiltercc if using assembler labels, but
only if mfiltercc can be found on the $PATH. The bootstrap compiler
may not have mfiltercc.

Add an option to the `mercury_config' script to make it easier to relocate a
Mercury installation.
scripts/mercury_config.in:
Add the option `--rebase', which acts as if the user passed the options
`--input-prefix <dir> --output-prefix <dir>', except that <dir> is
automatically guessed from the path to the `mercury_config' script.
(--input-prefix is undocumented)
If `mercury_config' is run without any arguments, and the input
directory doesn't exist, suggest the `--rebase' option as the user
probably moved the Mercury installation already.
Don't copy `Mercury.config.bootstrap' to the output directory.
Copy the regenerated `mdbrc' file to the output directory.
Set execute permissions on scripts copied to the output bin directory.
scripts/mercury_config.in:
Remember the original default grade that an installation was configured with
and use this as the "default" default grade when re-configuring. The reason
for doing this is that the default grade as chosen be configure when
re-configuring may not be among those installed. Users can still chose to
override the "default" default by setting MERCURY_DEFAULT_GRADE.

Move the intermodule analysis framework into the `compiler' directory, in
preparation for making it specific to the Mercury compiler, rather than having
it generic in case some fictional being might want to use it with a .NET
compiler one day. This will make it easier to use and modify.

Make it easier to boostrap the addition of new configuration
options.
scripts/Mercury.config.bootstrap.in:
A version of Mercury.config.in that does not contain
any options which are not understood by the installed
compilers. This is used when building the stage1 compiler.
Mercury.config is used to build the stage2 and stage3
compilers, and when running the tests. Mercury.config is
installed by `mmake install'.
Mercury.config.bootstrap.in is currently the same
as Mercury.config.in.

Move the setting of configuration options from mmc.in to
an options file Mercury.config. This has a few advantages:
- reduces the duplication between mmc and mercury.bat
- reduces the chance of running out of environment space
on crappy operating systems (although we probably exceed
the command line length limits on those systems anyway).
- makes it easier to bootstrap changes which add new
configuration options.
Always read the options files, even without `--make',
to avoid inconsistent behaviour.
scripts/Mercury.config.in:
New file containing the configuration code from mmc.in.
configure.in:
Create scripts/Mercury.config.
bindist/Mmakefile:
Make sure Mercury.config.in goes in the binary distribution.
Mmakefile:
bindist/Mmakefile:
Mmake.common.in:
Make sure we get the correct setting of INSTALL_PREFIX
when building the binary distribution.
scripts/Mmakefile:
scripts/mercury_config.in:
bindist/bindist.Mmakefile.in:
Install Mercury.config.
compiler/options.m:
doc/user_guide.texi:
Add documentation for the `--config-file' option, which gives
the name of the configuration file to read.
Add an option `read-config-file-2003-03-01' which will be
used in configure.in to test whether the compiler is up
to date after the configuration code is removed from mmc.in
(after this change is installed everywhere).
Add `--mercury-config-dir' as an abbreviation for
`--mercury-configuration-directory'.
Mmake.workspace:
Use the configuration file in scripts/Mercury.config.
browser/Mmakefile:
compiler/Mmakefile:
scripts/Mmake.vars.in:
Always pass ALL_MCFLAGS to mmc so that mmc will
use the configuration file specified in the options.
compiler/handle_options.m:
Handle the default value of `--config-file'.
compiler/mercury_compile.m:
Read the configuration file.
Always read the options files, even without `--make',
to avoid inconsistent behaviour.
compiler/make.m:
Pass the variable settings from the configuration file
to make__process_args.
The options files have already been read in mercury_compile.m,
so don't read them again here.
compiler/make.util.m:
Add a version of build_with_module_options which doesn't
need a make_info, for use by mercury_compile.m.
compiler/options_file.m:
Export a predicate to read a single options file.
Make the predicates to read options files add to an initial
options_variables map, rather than always creating a new one.
Allow MERCURY_STDLIB_DIR and MERCURY_CONFIG_DIR
to be set in the options file or environment.
scripts/mmc.in:
Set MERCURY_STDLIB_DIR and MERCURY_CONFIG_DIR in
mercury_compile's environment.

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.
Mmakefile:
runtime/Mmakefile:
scripts/Mmakefile:
Modify the `install' targets to store files needed to create
a new configuration in $INSTALL_LIBDIR/reconf.
runtime/Mmakefile:
Install mercury_conf.h in $INSTALL_LIBDIR/conf, rather than
$INSTALL_LIBDIR/inc, so that it can be overridden by a
different configuration.
scripts/mercury_config.in:
Create a new configuration, by creating part of a Mercury
source tree from the files stored in $INSTALL_LIBDIR/reconf,
running configure, then copying the files into a partial
installation tree.
scripts/Mmake.vars.in:
Define ENABLE_DEEP_PROFILER, for use by bindist/bindist.Makefile.
Define variables INSTALL_CONF_DIR (contains the files describing
the configuration) and INSTALL_RECONF_DIR (contains files needed
to reconfigure an installation).
configure.in:
Add an option `--enable-reconfigure', for use by
mercury_config.in.
Don't look for runtime/mercury_wrapper.c when checking
for the sources -- it isn't present when reconfiguring.
Look for scripts/mmc.in instead.
Look for the runtime headers in the installation hierarchy
rather than the `runtime/' and `trace/' directories when
reconfiguring.
Output the help message for the `configure' script to
`configure.help'. This is included in the help message
for `mercury_config'.
Add new configuration variables CONFIG_PREFIX and CONFIG_LIBDIR,
which are like PREFIX and LIBDIR except that they point
to the configuration files, not the library files.
In the normal case PREFIX and CONFIG_PREFIX will be the same.
bindist/bindist.INSTALL.in:
bindist/bindist.Makefile.in:
Use mercury_config to configure binary distributions.
bindist/Mmakefile:
bindist/bindist.configure.in:
bindist/bindist.build_vars.in:
Remove bindist.configure.in and bindist.build_vars.in.
compiler/options.m:
scripts/parse_ml_options.sh-subr.in:
scripts/mgnuc.in:
doc/user_guide.texi:
Add an option `--mercury-config-dir', and an environment
variable MERCURY_CONFIG_DIR, which tell the compiler and
scripts where to find the configuration files for the
installation.
MERCURY_CONFIG_DIR is not documented because it should
only be used by the scripts.
compiler/compile_target_code.m:
Pass `--mercury-config-dir' to the scripts.
compiler/handle_options.m:
Add `--c-include-directory $MERCURY_CONFIG_DIR/conf'.
library/getopt.m:
Handle `maybe_string_special' options.

Update the "Using a different C compiler" chapter.
