My already-proposed patch to fix basename/dirname introduced DOUBLE_SLASH_IS_DISTINCT_ROOT, which sounds like the right macro to base this decision on. Note, however, that while native compiles always define the macro correctly, a cross-compile must be pessimistic and assume that // might be distinct from / unless taught otherwise from config.cache, since there is no compile time test that will expose the target's file system characteristics in relation to / vs. // (at least not that I could come up with). > > It is not appropriate to change the dev_ino type, because it is used in > other contexts where the added space would be a pointless waste. Agreed, and I was planning on introducing a new type to store info on a doubled root. I'll work on a patch, and propose it once I get it hammered out alongside a repost of my basename/dirname patch. -- Eric Blake _______________________________________________ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
