+# configure.host
+#
+# This shell script handles all host based configuration for libstdc++.
+# It sets various shell variables based on the the host and the
+# configuration options.  You can modify this shell script without needing
+# to rerun autoconf/aclocal/etc.  This file is "sourced" not executed.
+#
+# You should read docs/html/17_intro/porting.* to make sense of this file.
+#
+#
+# It uses the following shell variables as set by config.guess:
+#   host                The configuration host (full CPU-vendor-OS triplet)
+#   host_cpu            The configuration host CPU
+#   host_os             The configuration host OS
+#
+#
+# It sets the following shell variables:
+#
+#   cpu_include_dir        CPU-specific directory, defaults to cpu/generic
+#                          if cpu/host_cpu doesn't exist.  This is not used
+#                          directly, but sets the default for others.
+#
+#   os_include_dir         OS-specific directory, defaults to os/generic.
+#
+#   c_model                the "C" header model, defaults to c_std.
+#
+#   c_compatibility        if "C" compatibility headers are necessary,
+#                          defaults to no.
+#
+#   abi_baseline_pair      directory name for ABI compat testing,
+#                          defaults to host_cpu-host_os (as per config.guess)
+#
+#   abi_tweaks_dir         location of cxxabi_tweaks.h,
+#                          defaults to cpu_include_dir
+#
+#   atomicity_dir          location of atomicity.h,
+#                          defaults to cpu_include_dir
+#
+#   atomic_word_dir        location of atomic_word.h
+#                          defaults to generic.
+#
+#   cpu_defines_dir        location of cpu_defines.h
+#                          defaults to generic.
+#
+# It possibly modifies the following variables:
+#
+#   OPT_LDFLAGS            extra flags to pass when linking the library, of
+#                          the form '-Wl,blah'
+#                          (defaults to empty in acinclude.m4)
+#
+#   port_specific_symbol_files
+#                          whitespace-seperated list of files containing
+#                          additional symbols to export from the shared
+#                          library, when symbol versioning is in use
+#
+#
+# If the defaults will not work for your platform, you need only change the
+# variables that won't work, i.e., you do not need to explicitly set a
+# working variable to its default.  Most hosts only need to change the two
+# *_include_dir variables.
+
