The --param patch works, thanks.

(please test with various options and in various situations).

That is a risky thing to ask ... I was just busy putting "all" options on, when I found this: [G4:~/gnu/testgpc/adriaan] adriaan% cat pedantic.pas program pedantic; const knil=nil; type double_t=double; begin end. [G4:~/gnu/testgpc/adriaan] adriaan% gpc -c pedantic.pas --gnu-pascal --pedantic pedantic.pas:2: error: ISO 7185 Pascal allows only simple constants pedantic.pas:3: error: ISO 7185 Pascal does not allow underscores in identifiers This may not be correct (for all other non ISO features a warning is given, not an error). Some results for other dialects: [G4:~/gnu/testgpc/adriaan] adriaan% gpc -c pedantic.pas --borland-pascal --pedantic pedantic.pas:2: error: ISO 7185 Pascal allows only simple constants [G4:~/gnu/testgpc/adriaan] adriaan% gpc -c pedantic.pas --mac-pascal --pedantic pedantic.pas:2: error: ISO 7185 Pascal allows only simple constants pedantic.pas:3: error: unknown identifier `double' [G4:~/gnu/testgpc/adriaan] adriaan% gpc -c pedantic.pas --ucsd-pascal --pedantic pedantic.pas:2: error: ISO 7185 Pascal allows only simple constants pedantic.pas:3: error: unknown identifier `double' [G4:~/gnu/testgpc/adriaan] adriaan% gpc -c pedantic.pas --delphi-pascal --pedantic pedantic.pas:2: error: ISO 7185 Pascal allows only simple constants pedantic.pas:3: error: ISO 7185 Pascal does not allow underscores in identifiers [I wonder if the feature of restricting language constructs with dialect options is worth the trouble maintaining it, except, of course, for both ISO standards, but, since the feature is there, I report whatever I find].
