Seems like it got lost in the transition to the new Makefiles. In 
configure.in is a bunch of lines for all the cpp examples. Copy one and 
change it for heteroAST. Rerun autoconf in the toplevel directory. And 
add the attached Makefile.in to cpp/examples/heteroAST rerun configure 
and you should be going...

Cheers,

Ric
