I wouldn't want to needlessly insist, but of course a canonical way to 
do this would be preferred.
I do see the %.i targets there in Rules.mk invoking the preprocessor, 
but I haven't yet figured how to make those execute.

Could you detail what make args would activate execution of the %.i targets?
This is not so important since for now Razvan's suggestion does the 
trick (or adding %.i as a dependency for %.o in Rules.mk),
but I thought it would be nice for future reference, so only respond 
when/if you have the time/disposition.

Thanks,
Corneliu.
