I have found multiple places where `fold' (from gcc-3.5-20040327)

Sounds like a bug in fold.

fold should preserve the type. If it doesn't, that is a bug in fold, submit code to call fold_convert or otherwise preserve the original type.

If your frontend doesn't build the tree with the right type, then it is a bug in your frontend, build it with a boolean type.
