Ack!  You should avoid the "portable" alloca() from GNU emacs at all
costs, as it is hideously slow and can consume *large* amounts of
memory.  Truly it is a last resort.  Surely Microsoft has alloca() in
one of the libraries.  AT&T keeps one in libPW, and GNU C has it built
in if you declare

#define alloca(n) __builtin_alloca(n)
