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