  22 # This is the GCC build-specific configuration file
  23 # where a configuration type is mapped to different system-specific
  24 # definitions and files.  This is invoked by the autoconf-generated
  25 # configure script.  Putting it in a separate shell file lets us skip
  26 # running autoconf when modifying build-specific information.
  27
  28 # This file switches on the shell variable ${build}.  As much of this
  29 # as possible should be replaced with autoconf tests in the future.
  30
  31 # This file sets the following shell variables for use by the
  32 # autoconf-generated configure script:
  33 #
  34 #  build_xm_defines     List of macros to define when compiling for the
  35 #                       build machine.
  36 #
  37 #  build_xm_file        List of files to include when compiling for the
  38 #                       build machine.
  39 #
  40 #  build_install_headers_dir
  41 #                       Target to use when installing header files.
  42 #
  43 #  build_exeext         Set to the suffix, if the build machine requires
  44 #                       executables to have a file name suffix.
