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

70# multiple symbol definitions are treated as errors, hence the
