That is correct for C99, but we don't have all of C99 yet.  Perhaps gcc
with certain options warns about it rtto help detect compatibility
problems.  I can't find any options that make it complain now.  ISTR
it complaining about even 0xFFFFFFFF because it is so large that it is
unsigned on 32-bit systems.

For C90 on 32-bit systems, 0x7FFFFFFFFF is constraint error.
0x7FFFFFFFFFLL is a syntax error for C90 on all systems.
