Thanks. I am not very fluent with the 64 bit extensions. In particular
the big number of registers and the conventions for variable number of
arguments calling make it complicated. I hope the interface will get
more polished once I find time to work on the PPC port.

I will look into this. Does it happen in the ECL core or in compiled code?
