+# This is the GCC build-specific configuration file
+# where a configuration type is mapped to different system-specific
+# definitions and files.  This is invoked by the autoconf-generated
+# configure script.  Putting it in a separate shell file lets us skip
+# running autoconf when modifying build-specific information.
+
+# This file switches on the shell variable ${build}.  As much of this
+# as possible should be replaced with autoconf tests in the future.
+
+# This file sets the following shell variables for use by the
+# autoconf-generated configure script:
+#
+#  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.
+#
+#  build_install_headers_dir
+#			Target to use when installing header files.
+#
+#  build_exeext		Set to the suffix, if the build machine requires
+#			executables to have a file name suffix.
+
+# Default settings.
