51 | # Mac OS X / Darwin's C preprocessor is Apple specific. It | |

53 | # and use GNU C's cpp. To do this we pass the -traditional-cpp | |
54 | # option to the compiler. Note that the -traditional-cpp flag | |
55 | # DOES NOT have the same semantics as GNU C's flag, all it does | |
56 | # is invoke the GNU preprocessor in stock ANSI/ISO C fashion. | |
57 | # | |
