I think most interest in C->Pascal header translators is for (semi)automated
translation of 3rd party library headers, not converting complete programs.
This means that it cannot be considered a given that a program exists that
uses all macros in the header.
Estabilishing rules or heuristics to judge if a macro could be a constant
would be useful though.
