Sorry for the CC. I was away and missed the discussion :)

Talk to the upstream author to use e.g. (GNU make specific):


or tell him to better use one of the following:

DEFS += -DVERSION="\"1.00\""
foo_CPPFLAGS += -DVERSION="\"1.00\""

These are normnally not overwritten by the user and the correct place to
leave a -D switch. There is enough documentation out there to find the
correct solution.

Read /usr/share/doc/make-doc/. There you find all built-in rules.

(Sorry, if you already got this information - I'm still
receiving/processing mails).
