- automake-1.4 sets default values for INCLUDES which we can't overwrite. - automake-1.5 renames this to DEFAULT_INCLUDES and leaves INCLUDES open for the developer to use. Thus for automake-1.4 we are forced to 'append' to INCLUDES and in automake-1.5 we can just set the value to whatever we like. Unfortunately, the behaviors of the two versions are mutually incompatible. The solution I am committing now works for both versions but automake-1.5 generates a lot of spurious warning messages that are annoying, but not fatal.
