It was a long time ago, but I expect it was just because alloca is
usually fine for memory that has to live for just a single function.
As a single-threaded program, GCC doesn't normally have severe limits
on stack size. This can't have been too big a problem, as I added the
code in GCC 4.2 and this is the first complaint I've seen.
In any case, as Steven points out, this has been fixed in mainline.
