Good point. Just for the record, this could be done today without
patching makedepend since there are already macros for handling extra
directories. This is what I was doing for my makedepend build before:
gccincdir=`${CC-gcc} -print-file-name=include`
echo "#define EXTRAINCDIR \"$gccincdir\"" >> makedepend-config.h.in
