Two non-AT&T compilers I remember wrangling with on U in the 1980's were Green Hills (on the Encore Multimax), and another compiler on some early flavor of ROMP or Power based IBM workstation. Maybe it was xlc? I remember one of them was unaware that case labels are valid ANYWHERE inside of a switch statement (the feature Duff applied so cleverly), something I discovered trying to bring up cfront (the original C++/C-with-classes compiler, that output C). On BDS C, I remember chatting with Leor Zolman: he was looking to contract someone to port BDS (Brain Damage Systems) C to the PC, but it was written in assembly language, so it wasn't a particularly attractive job. I don't recall him having a _particularly_ high opinion of the code, but I could be misremembering.
