> Of course that does not include large number of lines like 'VPATH = > @srcdir@'. Should also all these be replaced by 'vpath % @srcdir@'? No, that's not necessary. I tried grepping for ^VPATH.*=.*: and found only libgomp (where you can just remove the $(subst) invocation and change "VPATH =" to "vpath %") and libstdc++-v3. Thanks! Paolo
