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.
43
44# Default settings.
