+dnl Check for the presence of the Sun Studio compiler.
+dnl If Sun Studio compiler is found, set appropriate flags.
+dnl Additionally, Sun Studio doesn't default to 64-bit by itself,
+dnl nor does it automatically look in standard Solaris places for
+dnl 64-bit libs, so we must add those options and paths to the search
+dnl paths.
+
+dnl TODO(kenton):  This is pretty hacky.  It sets CXXFLAGS, which the autoconf
+dnl docs say should never be overridden except by the user.  It also isn't
+dnl cross-compile safe.  We should fix these problems, but since I don't have
+dnl Sun CC at my disposal for testing, someone else will have to do it.
