I think there was an explanation on the list a while back about how that error message pops out of the internals with that problem. But in general you're not going to go wrong by just single-quoting every argument of every Autoconf macro always. Once I started doing that, most of these odd problems went away, since the legacy stuff that didn't work properly with quoting is mostly gone now. The only exception is that sometimes I double-quote with [[ ]] for literal text with [] in it. Once in a blue moon there's some sort of bug with overquoting. But nearly all the weird problems people run into with Autoconf understanding its input are from underquoting some macro argument somewhere. -- Russ Allbery (rra@xxxxxxxxxxxx) <http://www.eyrie.org/~eagle/> _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
