In Tru64 autoconf likes to select "-std1" as the flag to get an ANSI compiler. The problem is that this is similar to the "-ansi" switch in GCC, and it turns off useful extensions. The normal and recommended switch would be just "-std". ¿Could this be fixed?
I'm attaching a patch that I think it fixes the problem by testing -std before -std1. I haven't tested it though.
Thanks.
