The version of g++ used in the hppa failing build mentioned above is 4.3.3.
It is the same version that I use to build the packages on my amd64 system.
Curiously enough, the automatic builds on armel [1] sparc [2] architectures
fail in the same way.  On the other hand, building on i386 [3] and amd64 (my
development system) succeeds.

Can that be caused by the way the int64 type is defined on some
architectures?
