What about the parallel changes to the sysdeps overrides?  I would
expect changes for hppa, mips, powerpc.  (Not sure about the alpha
situation.)

+CC libc-alpha which got lost in the thread.

Sure I can make it more explicit.

Will fix for v2.

I was not sure as some of the other patches in area don't seem to do that. Hence I
CC'ed Stephan who had earlier commented on x32.

This fix is only about the case where the *default* ABI in glibc requires 
these different values.

The header will need further changes (to use a conditional not based on 
__TIMESIZE) when _TIME_BITS=64 is supported on platforms that currently 
have 32-bit time_t.  That's the point at which changes for other 
architectures are needed - once we have an appropriate conditional for 
"the current compilation uses 64-bit time but kernel long is 32-bit" (or 
something like that).

I'm concerned the present patch is wrong for x32, however; that has 
__TIMESIZE == 64 && __WORDSIZE == 32 but should use the old values; the 
patch should be using __SYSCALL_WORDSIZE when available in place of 
__WORDSIZE.

Something like below ?

-#if __TIMESIZE == 64 && __WORDSIZE == 32

+#if TIMESIZE == 64 && (__WORDSIZE == 32 \
     && (!defined __SYSCALL_WORDSIZE || __SYSCALL_WORDSIZE == 32))

Also is it ok to littler the code (multiple times, this patch and else where) with
this or should we define a new __32BIT_ARCH_NOT_X32 or some such ?
