# 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.
