It's a more natural way of expressing alloca()....
First of all, the point that only gcc supports it isn't that important
since Linux already uses a _ton_ of gcc-isms. Second, C9X will add
support for the above to the official C language, so it isn't that evil.
Right, anyone who thinks it should ever be possible to compile the
Linux kernel with something with other than GCC is only kidding
themselves.
(For an amazingly good argument as to why this should be, go
investigate how one does inline assembly using the SunPRO
compiler, bleeech!)
