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.
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.
