+#
+# For build != host, we ask the installed GCC for the name of the tool it

+# 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.
