labrinea added a comment. Your suggestion that if all four options are mutually exclusive, then they should be a single integer option, totally makes sense to me. We could use a single integer option and make the old boolean flags deprecated (i.e. map '-fshort-enums' and 'fno-short enums' to the new integer option). My concern is that we have to be GCC compatible. I will communicate this to the GNU community.
