2017 - 1989 = 28.

Twenty-Eight Years. It would be kinda nice to move forward. Will 
we stick to C89 simply because of certain platforms that may never 
move forward? It's kinda like tying stones to one's legs. Or a 
lowest common denominator scenario.

Could you give an example/examples where the starting point for a 
bootstrap is C89 for the foreseeable future? (Not trying to be a 
nitpick pest, but actual data points are usually a good thing, and 
tcc supports only a few processors, so it would be nice to know 
which one and what platform, or is it some future thing.)

I like Larry's posting. Item 1 can also be done by text processing.

Or make a minimally functioning tcc C89 branch.

Or bootstrap it the Pascal P4 way.
