It wouldn't necessarily be up to the gcc team to deliver the preprocessor.
A 100% correct version would be substantial, as it would have to be a full
parser, but a more limited Perl or Python whack-job might handle almost
all the existing code.
The proposal is really only meant as an answer to those who say that we
cannot change the syntax at all because users won't want to change their
code.
