I am not sure what you mean here: bison.simple of 1.29f is the same as in
1.29d.

It may be easier to fix it when C++ is brought into the picture.

The part in bison.simple starting with "#ifndef YYSTACK_USE_ALLOCA" looks
messy and even wrong and should be changed. For example, one would expect
that if YYSTACK_USE_ALLOCA is not defined, then alloca is not used, but it
starts with
  # ifdef alloca
#  define YYSTACK_USE_ALLOCA 1
So that if <alloca.h> has been included somewhere, one gets alloca anyway.
