Not really.  If a compiler is buggy, the user should just use a newer
version.  Only if *no* working compiler for a specific platform
exists, should you try to work around it.  All this IMHO, of course.

No-one needed it yet, it seems; at least no-one asked for it, to the
best of my knowledge.

No it won't.  It's quite hard to detect whether you have exactly that
specific version of CW that's buggy, etc.  It *is* easy to detect whether
alloca() is available at all, and whether to include <alloca.h>, but that's
a different problem.
