Can you identify the consequence(s) of the difference? (At present Darwin relies on configuring —with-sysroot to reference the system SDKs, since there are no longer any headers installed in / on Darwin hosts) FWIW, we (FX and I) had started collating some of the Darwin libtool changes, (FX has posted one upstream aready IIRC) since we also want to land the necessary support for @rpath. > Reportedly libtool is based on upstream commit > 2c9c38d8a12eb0a2ce7fe9c3862523026c3d5622 I wonder if this will help track divergence. > (with *many* local changes, some of which may not be present upstream). maybe s/some/most/ ? ..
