66# option to the compiler.  Note that the -traditional-cpp flag
67# DOES NOT have the same semantics as GNU C's flag, all it does
68# is invoke the GNU preprocessor in stock ANSI/ISO C fashion.

71# multiple symbol definitions are treated as errors, hence the
72# -multiply_defined suppress option to turn off this error.
