# 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.
