More generally, $ORIGIN support (which is what a number of other linkers call it, IIUC) should be added completely if it's added, including a portable 'libtool' notation, testsuite coverage and fixing of fall-out, and correct treatment of the non-absolute paths throughout ltmain. I don't know how much work the latter would be, but guessing from the sysroot branch, there is work to do there. The most important question to this end is how to degrade gracefully on systems without such a feature. Cheers, Ralf
