-# answers. All we need to do is nab a few pieces of information.

-# 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.

-# 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.
