A worthy goal, but practically impossible. The different dialects of
Pascal aren't even lexically or syntactically compatible (as you found
out trying to make this change). We decided that the only practical
thing to do was to make a semi-custom version for each customer
(particularly as it is the wildly varying separate compilation features
of the different Pascal's that matter the most).
