You will get troubles anyway if address arithmetic is wrong:

  - on linux the stack is often above the 0x80000000,
I think (but I am not sure anymore) that on FreeBSD also the 
.text section is loaded above the 0x80000000 value...

- windows also (at least win95) does use addresses above 0x80000000
for system DLLs.

  So any error in using signed operation could
already break small program...
