Hi Luca and Dalibor,

That was I.

Just to re-iterate, the "configure" script tests the condition
"remainder of (0x80000000 // -1L)". On x86, it raises an arithmetic exeption
and the script sets the flag "LONG_MODULO_BROKEN".

The Motorola M68k series and (it would seem) the PowerPC series processors
do not generate an exception, but silently generate the wrong answer. 

Now, Dalibor, what happened to that patch I sent you months ago for
"configure"? You asked me to supply a similar patch for "configure.in" instead
of "configure", and I think I did, but if not, shall I send it again?
