Where did you read this?  This is what is written in the CPP and GCC manpages,
and the GCC online docs.

D - Like M except in two respects: it does not include the predefined macros,
and it outputs both the #define directives and the result of preprocessing. Both
kinds of output go to the standard output file. 

Neil, thanks for the suggestion, it removed all of them except for #define
__STDC_HOSTED__ 1, which I can take out with sed.
