+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:

+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a

+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+# for us.  In fact, there's no need even to look at the cache for the
+# answers.  All we need to do is nab a few pieces of information.
+# The intl directory is set up to make this easy, by generating a
+# small file which can be sourced as a shell script; then we produce
+# the necessary substitutions and definitions for this directory.

+# ACX_CHECK_INSTALLED_TARGET_TOOL(VAR, PROG)
+# Searching for installed target binutils.  We need to take extra care,
+# else we may find the wrong assembler, linker, etc., and lose.
+#
+# First try --with-build-time-tools, if specified.
+#
+# For build != host, we ask the installed GCC for the name of the tool it
+# uses, and accept it if it is an absolute path.  This is because the
+# only good choice for a compiler is the same GCC version that is being
+# installed (or we couldn't make target libraries), and we assume that
+# on the host system we'll have not only the same GCC version, but also
+# the same binutils version.
+#
+# For build == host, search the same directories that the installed
+# compiler will search.  We used to do this for the assembler, linker,
+# and nm only; for simplicity of configuration, however, we extend this
+# criterion to tools (such as ar and ranlib) that are never invoked by
+# the compiler, to avoid mismatches.
+#
+# Also note we have to check MD_EXEC_PREFIX before checking the user's path
+# if build == target.  This makes the most sense only when bootstrapping,
+# but we also do so when build != host.  In this case, we hope that the
+# build and host systems will have similar contents of MD_EXEC_PREFIX.
+#
+# If we do not find a suitable binary, then try the user's path.

+# AC_PROG_CPP_WERROR
+# Used for autoconf 2.5x to force AC_PREPROC_IFELSE to reject code which
+# triggers warnings from the preprocessor.  Will be in autoconf 2.58.
+# For now, using this also overrides header checks to use only the
+# preprocessor (matches 2.13 behavior; matching 2.58's behavior is a
+# bit harder from here).
+# Eventually autoconf will default to checking headers with the compiler
+# instead, and we'll have to do this differently.
+
+# AC_PROG_CPP_WERROR
+
+# Test for GNAT.
+# We require the gnatbind program, and a compiler driver that

+# Sets the shell variable have_gnat to yes or no as appropriate, and

+/* A note about endianness and swapping...
+
+   The RX chip is CISC-like in that the opcodes are variable length
+   and are read as a stream of bytes.  However, the chip itself shares
+   the code prefetch block with the data fetch block, so when it's
+   configured for big endian mode, the memory fetched for opcodes is
+   word-swapped.  To compensate for this, the ELF file has the code
+   sections pre-swapped.  Our BFD knows this, and for the convenience
+   of all the other tools, hides this swapping at a very low level.
+   I.e.  it swaps words on the way out and on the way back in.
+
+   Fortunately the iovector routines are unaffected by this, so we
+   can use them to read in the segments directly, without having
+   to worry about byte swapping anything.
+
+   However, our opcode decoder and disassemblers need to swap the data
+   after reading it from the chip memory, just like the chip does.
+   All in all, the code words are swapped four times between the
+   assembler and our decoder.
+
+   If the chip is running in little-endian mode, no swapping is done
+   anywhere.  Note also that the *operands* within opcodes are always
+   encoded in little-endian format.  */
