That said, given that using -traditional-cpp for .S assembly source
pre-processing brings in subtle differences in pre-processor syntax
between our c and assembly language source files, is there any reason
_we_ should continue to use -traditional-cpp?

Are there any platforms where gas/gcc do not provide a
modern-cpp-friendly assembly syntax?
