This is really strange since in port.c, you have PPC assembler code (yes, I
have been working with computers long enough to recognize the difference
between Intel - including it derivatives - and PowerPC along with another other
kinds of processor you may bring up assembly code) which will not run under
Intel unless there is a PPC emulator.

Code from Port.c:
#elif defined(__powerpc__) && defined(__APPLE__)
__ASM_GLOBAL_FUNC( wine_switch_to_stack,
                   "mtctr r3\n\t" /* func -> ctr */
                   "mr r3,r4\n\t" /* args -> function param 1 (r3) */
                   "mr r1,r5\n\t" /* stack */
                   "subi r1,r1,0x100\n\t" /* adjust stack pointer */
                   "bctrl\n" /* call ctr */
                   "1:\tb 1b") /* loop */
#elif defined(__powerpc__) && defined(__GNUC__)
__ASM_GLOBAL_FUNC( wine_switch_to_stack,
                   "mtctr 3\n\t" /* func -> ctr */
                   "mr 3,4\n\t" /* args -> function param 1 (r3) */
                   "mr 1,5\n\t" /* stack */
                   "subi 1, 1, 16\n\t" /* allocate space for the callee */
                   "li 0, 0\n\t" /* load zero */
                   "stw 0, 0(1)\n\t" /* create a bottom stack frame */
                   "bctrl\n\t" /* call ctr */
                   "1:\tb 1b") /* loop */


I am well aware that code compiled for one computer will not run on another
computer with a different processor type which is why the compilation process
from a common higher level code in the first place.

I am also aware that Wine is not a emulator; but, it can run on top of an
emulator such as qemu if I can just qemu to recognize a Wine build.
