I'm sorry, but I don't understand: if some interface is not supported by the standard, I don't want it... because if I use something outside the standard I cannot reasonably expect some other c99 compiler to support it. Surely ? I try to be reasonably conservative and I wouldn't have much sympathy with a compiler that doesn't cover the c99 things I do use.
It is true that useful programs can be written using nothing more than ANSI C interfaces (e.g. stdio). Most programs want to use more than that though. For example, they may want to use POSIX standard interfaces which are not included in the ANSI C specification.
The problem is that there is only one control knob being exposed. I assume that you want to block GNU C compiler specific language features while being able to use more than ANSI C interfaces. This would require more than one control knob.
