I'd certainly support dropping c-alloca support from libiberty. I totally agree that it's only purpose was to support ancient compilers. I don't think I've seen c-alloca being used since the late 90s and I think we started dropping all the alloca (0) that existed solely to support c-alloca eons ago. jeff
