Use "-no-cpp-precomp" rather than "-traditional-cpp" on MacOS X, as per

the "The Compiler and Tools" section on

	http://fink.sourceforge.net/doc/porting/basics.php

Do so on MacOS X regardless of whether the compiler is called "gcc" or
not, as that page also indicates that the compiler is installed as "cc".
