That should work better ;-) Or just use the "-traditional-cpp" option, i.e. "gcc -E -traditional- cpp". > Note that IIRC with gcc cpp, -x assembler also means > that # won't be handled as a cpp directive except in column 0 which is > also an advantage for us, although no longer essential with your > escaping support. Not all cpps have an equivalent option, though. 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.
