I've considered the potential disruption of deprecating `.gch` files but haven't been able to substantiate it (let's say the concern is about autotools users). When using the regular expression `-o.*\.gch`, I've found very few examples, and it's likely that many of them are not affected since many builds place an `-include`d file alongside a `.gch` file.
