Yes, but on the other hand they have a precision and a range. > There are not many references to BOOLEAN_TYPE in ada/gcc-interface > thus it shouldn't be hard to change ... (looks like Ada might even prefer > ENUMERAL_TYPE here). It was like that originally (an ENUMERAL_TYPE) but this blocked LTO (well, cross-language LTO) exactly like the sizetype discrepancy, so I don't really feel like going back in time. -- Eric Botcazou
