+# generates numerous errors and warnings.  We want to bypass it
+# and use GNU C's cpp.  To do this we pass the -traditional-cpp
+# option to the compiler.  Note that the -traditional-cpp flag
+# DOES NOT have the same semantics as GNU C's flag, all it does
+# is invoke the GNU preprocessor in stock ANSI/ISO C fashion.
+#
+# Apple's linker is similar, thanks to the new 2 stage linking
+# multiple symbol definitions are treated as errors, hence the
+# -multiply_defined suppress option to turn off this error.
