This style with local.mk perhaps comes from an age where Automake was not as 
smart. I use a Makefile.am.

In addition, it might benefit from using say a 
  #define YYSTYPE double
to illustrate how one sets ones own type.

This is the only preprocessor macro that remains in the C++ parser, so perhaps 
it should be replaced with a 
  %semantic-type {...}
or something.
