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.
