Add '-undef' to DTS_CPPFLAGS to avoid unwanted expansion of dts content that matches system-specific or gcc-specific predefined macros.
Example: A number of PowerPC related *.dts files in the kernel define a property named 'linux,network-index' which (w/o '-undef') is expanded to '1,network-index' by the preprocessor because of '#define linux 1.'
i think you should use -ansi instead. that's what we use in other places for the same reason.
this would increase the probability of a name clash.
no idea what you're talking about. have you actually looked at the output of `gcc -E -dD -ansi` ?
$ gcc -E -dM -ansi - </dev/null | wc -l 229 $ gcc -E -dM -undef - </dev/null | wc -l 2
and ? did you *look* at the output ? they're all of the form __foo__. do any device trees really use __foo__ names ? i don't think so. -mike
