Program QNX 6.1 to QNX 4.25

I have a embedded card ELAN-PC104 with QNX 4.25 and a PC desktop with QNX
6.1.
Is there a solution to compile a program under QNX 6.1 and send it to my
embedded card and it work correctly? When I do this step, the result is this
error : “SIGSEGV” !

You cannot build QNX4 program with QNX6.

It MIGHT be possible to get gcc to build QNX4
executable providing you copy the QNX4 header file and library
over QNX6, but that will probably take LOT of tweaking.
