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