# Defaults for GCC are used if not supplied.  Note that CXXFLAGS should
# include optimizations intended to be used.  It is assumed that the
# compiler uses -S to produce assembly output and -o - works to get that
# output on stdout, and -Dsym=val is used to define preprocessor symbols.
#
# Note that debugging symbols should not be included as generally the
# debugging info contains references to elided calls etc.
