52# generates numerous errors and warnings.  We want to bypass 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.

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