Fails to build for win32:

/home/petmay01/linaro/qemu-for-merges/target-alpha/int_helper.c: In
function ‘helper_zapnnot’:
/home/petmay01/linaro/qemu-for-merges/target-alpha/int_helper.c:48:
warning: integer constant is too large for ‘unsigned long’ type

64-bit constants should always have the 'ULL' or 'LL' suffixes.
'UL' and 'L' suffixes are almost always a bug, because they
don't work for 64-bit constants and are overkill for 32-bit
constants (where no suffix or just 'U' would do).

Oops, yes indeed.
