I have not tried it yet, but it looks like it will mostly work.
It won't work on any hosting platform that doesn't provide strtoll() or
"long long" though (assuming something outside of my own changes does
need strtoq() or strtouq()). The configure.in should probably also do:
AC_CHECK_TYPES([long long, unsigned long long])
and then do something appropriate with any failure of that test.
Also for GNU Autoconf the CPP test should be "#ifndef HAVE_U_QUAD_T".
Note too that as far as I can tell nothing in C99 really requires that
sizeof(u_quad_t) be the same as sizeof(unsigned long long), i.e. that
"unsigned long long" be restricted to a 64-bit representation (otherwise
we'd only have one implementation of strtoll() in NetBSD's libc too,
instead of a nearly identical one being called strtoq() :-). Of course
this won't likely break anything until someone tries to build NetBSD on
a 128-bit machine (and assuming some build tool does need strtoq() or
strtouq() at the time). :-)
