------- Comment #10 from rguenth at gcc dot gnu dot org  2009-07-04 19:18 -------
"/Qauto-ilp32 (-auto-ilp32): Specifies that the application cannot exceed
a 32-bit address space, which allows the compiler to use 32-bit pointers
whenever possible."

so it does in fact not change the ABI?  I don't see how this will be useful
without kernel / libc support.
