How to port GMP 4.2.2 on QNX6

I am trying to port GMP 4.2.2 on a powerpc603e which run QNX. but i could not found any solution. giving --host=none actually generates the makefile but i think this does not use the powerpc processor specific optimization that GMP provides. Can somebody tell me what are changes neded?

First you’ll need to explain what GMP is. Next you’ll need to clarify what your development host is. I am assuming that you do not have a powerpc603e based development host (it is possible with QNX, but you’d be the first person I have heard of with one).
