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.
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.
29 # This file sets the following shell variables for use by the
30 # autoconf-generated configure script:
32 # build_xm_defines List of macros to define when compiling for the
35 # build_xm_file List of files to include when compiling for the
38 # build_install_headers_dir
39 # Target to use when installing header files.
41 # build_exeext Set to the suffix, if the build machine requires
42 # executables to have a file name suffix.
48 build_install_headers_dir=install-headers-tar
51 # System-specific settings.
