My point was not entirely that the documentation was wrong. It is an extremely useful capability to be able to define a common base set of CPPFLAGS and then use per-target CPPFLAGS to extend these (equivalent to +=). Otherwise the Makefile.am has to be very messy and large, since as soon as you add one per-target CPPFLAGS, you then need to start passing all CPPFLAGS via individual per-target CPPFLAGS The current operation of INCLUDES in conjunction with per-target CPPFLAGS is effectively INCLUDES=$(CPPFLAGS) TARGET_INCLUDES=$(INCLUDES) $(TARGET_CPPFLAGS) Bob ====================================== Bob Friesenhahn [EMAIL PROTECTED] http://www.simplesystems.org/users/bfriesen
