+dnl Determine the s&m files to use
+dnl ------------------------------
+dnl Given the configuration name, set machfile and opsysfile to the
+dnl names of the m/*.h and s/*.h files we should use.
+dnl Canonicalize the configuration name.
+XE_STRIP_4TH_COMPONENT(ac_cv_build_alias)
+XE_STRIP_4TH_COMPONENT(ac_cv_build)
+AC_SUBST(configuration, $ac_cv_build)
+dnl If you add support for a new configuration, add code to this
+dnl switch statement to recognize your configuration name and select
+dnl the appropriate operating system and machine description files.
+dnl You would hope that you could choose an m/*.h file pretty much
+dnl based on the machine portion of the configuration name, and an s-
+dnl file based on the operating system portion.  However, it turns out
+dnl that each m/*.h file is pretty manufacturer-specific - for
+dnl example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
+dnl all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
+dnl machines.  So we basically have to have a special case for each
+dnl configuration name.
+dnl As far as handling version numbers on operating systems is
+dnl concerned, make sure things will fail in a fixable way.  If
+dnl /etc/MACHINES says nothing about version numbers, be
+dnl prepared to handle anything reasonably.  If version numbers
+dnl matter, be sure /etc/MACHINES says something about it.
+dnl Eric Raymond says we should accept strings like "sysvr4" to mean
+dnl "System V Release 4"; he writes, "The old convention encouraged"
+dnl "confusion between `system' and `release' levels'."
