Hmm... there are a few additional cases where C is simply inappropriate:
1) You want to check for integer overflow.
2) You need exceptions.
Oh, and slightly off-topic, there are a few other things that annoy
those who want to use C as a backend for their compiler:
3) It has no support for tail call recursion.
4) It has no support for automatic garbage collection.
(The following are from http://www.cminusminus.org/faq.html:)
5) It cannot return multiple values in registers
6) It cannot bind global variables to registers
7) It has no support for lightweight concurrency
Not all of these features are required for each language, but many
(most?) languages need at least one of them.
