(This was just a quick grep for "long" in xen/include/public.)
Of course, pointers have the same problem. Thankfully, it seems
pointers are
mostly found in the same list of offenders. (It's also a little harder
to
grep for "*", so I could be missing some problems.)
How about writing a script that converts the Xen public headers into a
set that, when compiled on 32-bit ppc, match the 64-bit ppc layout?
That might be saner than trying to manually finesse our headers around
the ppc abi so that building in 32-bit or 64-bit environment both
happen to give same binary layout.
