Thank you, that was the case. Suggested by your answer, I have found
an interesting discusssion in fpc-devel archives. ($calling fpccall
should be relalced by oldfpccall, I guess.)
Keeping stack-based convention is slower, but this has minor
meaning for me, as I save much more time by putting inner loops into
registers (thousands operations per typical call) than I waste using
stack frame (one time per call). However, the first operation to be
done is to load addresses from stack to registers and I think that
should be avoided using new convention.
