Every compiler is a bit different ... but this looks like the kind of case where you could file an RFE and get something changed. The two arguments of "gcc does it this way so it's a barrier to interoperability" and "the warning doesn't actually help anyone do anything" would probably be effective. -- James Carlson, Solaris Networking <james.d.carlson at sun.com> Sun Microsystems / 35 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677
