Very good point. Yes, I confirm, after "make maintainer-clean", the gperf-generated .h files differ when built through "make" from a subdir vs. through "make" from the source dir. For some .y files, I already encountered and eliminated the issue [1]; for .gperf files, I still need to do it. It's easy to do: Just some post-processing with 'sed'.
