I see, thank you for the explanation. Right now I am working on the variant of the patch that consolidates the -L/-rpath flags in lib.mk, do you think it will be of use to have some opt-in/opt-out mechanism, or just impose them unconditionally, similarly to -D_GNU_SOURCE? So far I don't see any issues with either building or running the tests, but I can imagine it might be necessary to avoid such flags in some cases. > I had to comment on all 3 patches you sent - instead I could have > sent one reply to the cover letter.
