Hi Greg,

below you can see the report with the error on m68k. It was sent to me from a
test robot of intel.

According to my research, this problem occured, because there is no hardware
support for floating point on the m68k (or it was configured not to use it).
Therefore gcc uses an internal function, provided by libgcc. Obviously libgcc
wasn't linked...

I don't know how to come arround this problem by modifying my code (except
reducing the accuracy of the calculation by not using floating point).

Can we ignore the error or can I do something else?
Maybe a special include just in case of m68k can help??!?
I don't have an environment for building m68k.

It looks like a 64bit issue, try wrapping your division in that function
with a call to do_div() like you do elsewhere in that function.  That
should solve the issue.

thanks,
