@whitequark @wyatt8740 @jannem @dalias @unnick question: what if csh from 1989 is the only scripting language available to you, and there's no compilers available on a target system except K&R as? i'm working on a project where this is the entire issue, and it's... not fun. this is the precise case where that "consider using bash to build GCC because some cases in other shells make the ./configure script take literal days" warning actually happens lol
