Maybe you used "-x assembler-with-cpp"? That should work better ;-) Or just use the "-traditional-cpp" option, i.e. "gcc -E -traditional- cpp".

This is how the traditional C pre-processor behaves. I don't think this is exactly what matters for DTS, or does it ever happen that you have a # preceded only by whitespace? The # and ## stringification and token pasting ops will of course bite you with the ISO C pre- processor, indeed.
