Makefile.in (config.status): Depend on config.gcc.

	* Makefile.in (config.status): Depend on config.gcc.
	* configure.in <for machine in $build $host $target>: Move
	contents of loop into config.gcc, removing autoconf quoting.
	Fix changequote bug for alpha*-*-vxworks*.
	* configure: Regenerate.
	* config.gcc: New.

+# This is the GCC build-, host- and target-specific configuration file
+# where a configuration type, as recognized and generated by config.bfd,
+# is mapped to different system-specific definitions and files.  This is
+# invoked by the autoconf-generated configure script, called for build,
+# host and target in that order, setting ${machine} to each.  Putting it
+# in a separate shell file lets us skip running autoconf when modifying
+# build-, host- and target-specific information.
+
+# This file switches on the shell variable ${machine}, and also uses the
+# following shell variables:
+#
+#  with_*		Various variables as set by configure.
+#
+#  enable_threads_flag	Either the name, yes or no depending on whether
+#			threads support was requested.
+#
+#  gas_flag		Either yes or no depending on whether GNU as was
+#			requested.
+#
+#  gnu_ld_flag		Either yes or no depending on whether GNU ld was
+#			requested.
+
+# This file sets the following shell variables for use by the
+# autoconf-generated configure script:
+#
+#  cpu_type		The name of the cpu, if different from machine.
+#
+#  tm_file		A list of target macro files, if different from
+#			"$cpu_type/$cpu_type.h".
+#
+#  tm_p_file		Location of file with declarations for functions
+#			in $out_file.
+#
+#  out_file		The name of the machine description C support
+#			file, if different from "$cpu_type/$cpu_type.c".
+#
+#  md_file		The name of the machine-description file, if
+#			different from "$cpu_type/$cpu_type.md".
+#
+#  tmake_file		A list of machine-description-specific
+#			makefile-fragments, if different from
+#			"$cpu_type/t-$cpu_type".
+#
+#  float_format		Set to the symbolic name for the floating-point
+#			formats used for this machine, if different from
+#			"i64".  Used to derive a header file name to
+#			include, like "vax" for "float-vax.h".  If no such
+#			file is wanted, set to "none".
+#
+#  extra_objs		List of extra objects that should be linked into
+#			the compiler proper (cc1, cc1obj, cc1plus)
+#			depending on target.
+#
+#  extra_headers	List of used header files from the directory
+#			ginclude.
+#
+#  host_xmake_file	List of host-specific makefile-fragments.
+#
+#  extra_passes		List of extra executables compiled for this target
+#			machine, used for compiling from source to object.
+#
+#  extra_parts		List of extra object files that should be compiled
+#			for this target machine.
+#
+#  extra_programs	Like extra_passes, but these are used when linking.
+#
+#  host_extra_objs	List of extra host-dependant objects that should
+#			be linked into the compiler proper.
+#
+#  extra_objs		List of extra target-dependant objects that should
+#			be linked into the compiler proper.
+#
+#  host_extra_gcc_objs	List of extra host-dependant objects that should
+#			be linked into the gcc driver.
+#
+#  build_xm_defines	List of macros to define when compiling for the
+#			build machine.
+#
+#  build_xm_file	List of files to include when compiling for the
+#			build machine.
+#
+#  host_xm_defines	List of macros to define when compiling for the
+#			host machine.
+#
+#  host_xm_file		List of files to include when compiling for the
+#			host machine.
+#
+#  xm_defines		List of macros to define when compiling for the
+#			target machine.
+#
+#  xm_file		List of files to include when compiling for the
+#			target machine.
+#
+#  use_collect2		Set to yes or no, depending on whether collect2
+#			will be used.
+#
+#  target_cpu_default	Set to override the default target model.
+#
+#  build_install_headers_dir
+#			Target to use when installing header files.
+#
+#  md_cppflags		Non-empty list of args to pass to cpp if the target
+#  			wants its .md file passed through cpp.
+#
+#  host_truncate_target
+#			Non-empty if the target name should be truncated
+#			on this host, due to filename length issues.
+#
+#  gdb_needs_out_file_path
+#			Set to yes if gdb needs a dir command with
+#			`dirname $out_file`.
+#
+#  build_exeext		Set to the suffix, if the build machine requires
+#			executables to have a file name suffix.
+#
+#  host_exeext		Set to the suffix, if the host machine requires
+#			executables to have a file name suffix.
+#
+#  thread_file		Set to control which thread package to use.
+#
+#  gas			Set to yes or no depending on whether the target
+#			system normally uses GNU as.
+
+# The following variables are used in each case-construct to build up the
+# outgoing variables:
+#
+#  xmake_file		Makefile-fragment when this system is as a host,
+#			for host_xmake_file.
+#
+#  extra_host_objs	List of extra objects that should be linked into
+#			the compiler proper when this system is a host,
+#			for host_extra_objs.
+#
+#  install_headers_dir	Makefile-target for how the header file directory
+#			is installed, when this system is a build system,
+#			for build_install_headers_dir.
+#
+#  truncate_target	Non-empty if the target name should be truncated
+#			when this system is a host, due to filename length
+#			issues.  For host_truncate_target.
+#
+#  exeext		The suffix for executables on this system.
+#
+#  gnu_ld		Set to yes or no depending on whether the target
+#			system normally uses GNU ld.
