I think you can configure a perl with 'use64bitint' on a 32-bit
architecture iff the compiler supports the 'long long' type.
Maybe that doesn't matter wrt what you're trying to do (though
your original post specified 64-bit architectures) ....

Ah, that's just because it was the obvious common factor in where
the test failures had occurred; no informed judgement was involved.

or maybe there's a need to also check $Config{longsize} ...

I went with longsize, because the offending variables are defined as
unsigned long, and because then if I test $Config{longsize} ne '4'
hopefully it will deal with 128-bit and 256-bit machines too.

Crypt-Tea_JS-2.19.tar.gz seems to work perfectly, and is about to hit
the mirrors :-)

Thanks again for your help, Regards, Peter
