| # 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. | |
