maybe ? automake & libtool haven't been doing this, so i'm not sure how useful such a test would be in practice. and what would autoconf do if it didn't think `ar` is compatible ? issue an error & abort ? > and maybe also check whether it's going to spew "`u' modifier ignored since > `D' is the default (see `U')" messages like current binutils ar tends to (see > e.g. https://bugzilla.redhat.com/show_bug.cgi?id=1155273 -- as far as I can > tell the message is harmless, but if we can reduce the number of junk bug > reports that random autotools-using projects have to field, that's a Good > Thing). similarly, what are you expecting autoconf to do with this information ? should we ignore that `ar` ? or it wrap it ? or do something else ? -mike
