I have responded to Michael, but I thought I should probably send something to the list too. The main reason for GCC on IA64 HP-UX defaulting to 32 bit mode is because that is also the default for the HP compiler on IA64 HP-UX. I don't think I like the idea of changing the default on GCC to be different then HP's compiler. But having a different target name like ia64w-hp-hpux11* where the default is 64 bits seems reasonable if it is needed. Steve Ellcey sje@xxxxxxxxxx
