There is an apparently undocumented libc routine in 4.1 called alloca, which
seems to do exactly what you want.  Here is the header information from
alloca.s:

# @(#)alloca.s	4.1 (Berkeley) 12/21/80
# like alloc, but automatic
# automatic free in return

I have never tried it, but discovered it one day while peering into the
recesses of the libc sources.  Does anybody know which UNIX programs use it?
