Thanks for spotting this warnings, Stuart.
Actually, it seems that "AUTOMAKE_OPTIONS = nostdinc" makes a better job,
as I don't seem to have to redefine DEFAULT_INCLUDES at all when using the
option.
The question still remains though: Is this a good enough way to solve the
problem? Going off from the defaults seems not very good, but at the same
time, having -I. as default looks strange to me...
Shall I create a patch with this...?
