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.
