Any change to gram.y regenerates the local copy of parse.h and affects
other files *in that local directory* (as well as elsewhere). The
makefile *in that local directory* should be able to make the other
files *in that same directory* at the same time.

That's my point ;)

istm that the local makefile should at least reach up and over to the
other rule for building parse.h (wherever that is), so that parse.h gets
moved to the include/ area. If make is invoked from the top of the tree,
then it is a noop. If make is invoked from backend/parser/, then the
local files get rebuilt correctly.
