	Instead of substituting in an arbitrary shell script when
	processing `--pre-link-command' and `--extra-init-command',
	require that these options specify a command which will
	be passed the name of the source file containing the main
	module as the first argument, with the source files containing
	the remaining modules following. This is simpler and avoids
	dependencies on a shell.

Nothing. I've removed that.

Remove Unix dependencies in the compiler.

Avoid calling passes_aux.invoke_shell_command, which
requires the presence of a Unix shell.

The implementation of fact tables still has dependencies
on Unix utilities (e.g. sort).

aclocal.m4:
	Don't pass Unix style paths to MSVC.

configure.in:
	Use `cygpath -m' rather than `cygpath -w'.
	`cygpath -m' uses '/' as the directory separator,
	so it doesn't cause quoting problems in shell
	scripts.

	Apply $CYGPATH to $PREFIX, $LIBDIR, $CONFIG_PREFIX
	and $CONFIG_LIBDIR.

	Don't pass `-lm' when linking with MSVC.

configure.in:
compiler/options.m:
scripts/Mercury.config.in:
	Add extra configuration options to deal with differences
	between linking with gcc and MSVC:
		--linker-opt-separator
		--linker-link-lib-flag
		--linker-link-lib-suffix
		--shlib-linker-link-lib-flag
		--shlib-linker-link-lib-suffix
		--linker-path-flag

NEWS:
doc/user_guide.texi:
compiler/options.m:
compiler/compile_target_code.m:
compiler/make.program_target.m:
	Instead of substituting in an arbitrary shell script when
	processing `--pre-link-command' and `--extra-init-command',
	require that these options specify a command which will
	be passed the name of the source file containing the main
	module as the first argument, with the source files containing
	the remaining modules following. This is simpler and avoids
	dependencies on a shell.

	Fix quote_arg to handle Windows paths better.

	Add an option `--no-make-implies-use-subdirs', which
	is handy when using `mmc --make' with a workspace
	built without `--use-subdirs'. Library installation
	doesn't work with `--no-make-implies-use-subdirs'.

compiler/handle_options.m:
	Don't attempt to use symlinks if they're not available.

	Handle --no-make-implies-use-subdirs.

compiler/make.util.m:
	Handle --no-make-implies-use-subdirs.

compiler/compile_target_code.m:
	Be more careful about quoting.

	Don't call invoke_shell_command where invoke_system_command
	would do.

	Allow linking using MSVC.

compiler/modules.m:
	Remove make_directory, which is now implemented by dir.m.

	Use io.make_symlink rather than shell scripts.

	Implement mercury_update_interface in Mercury.

compiler/llds_out.m:
compiler/make.program_target.m:
	Use dir.make_directory, not modules.make_directory,
	which has been removed.

compiler/make.module_target.m:
	Invoke mercury_compiler directly, not through the
	mmc script to avoid shell dependencies.

	If we can't fork() child `mmc --make' processes,
	pass the arguments to the child process using a
	file to avoid overflowing system limits on Windows.

compiler/mercury_compile.m:
compiler/options_file.m:
	Read argument files.

	Handle backslash-newline in options files correctly.

compiler/passes_aux.m:
	invoke_system_command shouldn't set the exit status --
	the caller may be able to try something else.

compiler/process_util.m:
	Export can_fork for use by make.module_target.m.
	
	Remove hacks to work around bugs in the implementation
	of zero-arity foreign procs.

compiler/prog_io.m:
	Handle bizarre file names without aborting.

library/Mmakefile:
library/print_extra_inits:
	Move code to find extra initialization functions into
	print_extra_inits, due to the change to the handling
	of the --extra-init-command option described above.

scripts/mercury.bat.in:
	Make this actually work.

tools/bootcheck:
	Set ANALYSIS_LIB_NAME.

	Apply cygpath (-m not -w) to $root.

	Link print_extra_inits into the stage2 and stage3
	library directories.

util/mkinit.c:
	Handle '\\' in path names.
