Sorry, I don't understand how alloca-opt works. Doesn't it invoke
AC_FUNC_ALLOCA? And doesn't that mean that the user must put
$(ALLOCA) into ..._LIBADD? And won't that break on hosts that don't
have alloca?
Also, with alloca-opt, isn't a program supposed to inspect HAVE_ALLOCA
before attempting to invoke alloca? The Bison-generated code doesn't
do that; instead, it inspects YYSTACK_USE_ALLOCA, defined (alloca),
defined (_ALLOCA_H), and defined(__GNUC__) to decide whether to use
alloca. Since it includes <alloca.h>, _ALLOCA_H will be defined, so
it will use alloca, even though alloca doesn't exist.
