Okay. I have incorporated your changes into my patch, added the
CONST_INT check, and am running a bootstrap on ia64-hpux; if it
succeeds I'll repost the combined patch.

I am willing to do this for most breaks.
However, it is my understanding that breaks that affect only Ada are
*not* considered critical, and in fact that there is no obligation for
anyone to attempt to build the Ada front end. I normally do not
bother building it even on platforms that can handle it (ia64-hpux
cannot, as the runtime has not been ported). This is why I did not
respond very fast to this bug report. I am willing to change my
habits if the policy has changed, but not otherwise.

Sure, I'll look at that.
