  27 # Mac OS X / Darwin's C preprocessor is Apple specific.  It
  28 # generates numerous errors and warnings.  We want to bypass it
  29 # and use GNU C's cpp.  To do this we pass the -traditional-cpp
  30 # option to the compiler.  Note that the -traditional-cpp flag
  31 # DOES NOT have the same semantics as GNU C's flag, all it does
  32 # is invoke the GNU preprocessor in stock ANSI/ISO C fashion.
  33 #
  34 # Apple's linker is similar, thanks to the new 2 stage linking
  35 # multiple symbol definitions are treated as errors, hence the
  36 # -multiply_defined suppress option to turn off this error.
