--- Comment #8 from Paolo Carlini <paolo.carlini at oracle dot com> --- Hi. As you can see, the patch itself seems simple, but a while ago I noticed that quite a few testcases would need adjusting and that made me a little nervous. In particular those testcases (both C and C++) which are doing more than one check and would have to be split, because the compilation ends after the first #error. Anyway, probably that's just boring work to do, what about the other compilers? For sure some are following the current gcc behaviour, for compatibility, I suspect ICC for example. Should we also have a command line switch? Probably missing #includes just unconditionally end the compilation on most compilers, though. Well, it's also true that the so called workaround which I mentioned in Comment #1 works pretty well and we do have *very* few fatal errors in the front ends...
