Hi there, Matthias Klose (doko, CCed) added a patch to Ubuntu's ghc to pass these flags to ld on linux arches. Should we take this change in Debian too? I understand that the last two will be switched to being the default in ld soon. We should likely follow, and it is the only change that Ubuntu has over Debian. @doko, why did you limit to *-linux*? For --hash-style=both? Could you generalise the patch for Debian (or let us know on which arches things work)? Attached. Thanks, -- Iain Lane [ iain@orangesquash.org.uk ] Debian Developer [ laney@debian.org ] Ubuntu Developer [ laney@ubuntu.com ] PhD student [ ial@cs.nott.ac.uk ]
