But still needs the use of need-formatstring-macros, and gettext 0.16.1

The uses of these formatstring macros require

Hi Eric,
My understanding is that on 64-bit windows,
sizeof(long)==4 but sizeof(void*)==8; and ... sizeof(size_t) is also 8.
Yes, correct.
Which means you _can't_ use %lu,(unsigned long)size_t_val.
You _can_ use this. It will work as long as each of your program's data
structures is less

In a quick google search, I found this use of PRIdS (which is geared
more for ssize_t, but the analog PRIuS would apply to size_t):

However, S is awfully short; I'd
What a shame that POSIX omitted an inttypes.h PRIu* for size_t.
You can define it by yourself ...
Or use uintptr_t instead of size_t. By the definition of these types,
you can be sure that uintptr_t is at least as wide as size_t. Then use
printf (% PRIuPTR, (uintptr_t) size_t_value);

libvirt is currently LGPLv2+, but needs to use the printf family of
functions to display size_t values, even on mingw where %zu support is
not built in. My understanding is that on 64-bit windows,
sizeof(long)==4 but sizeof(void*)==8; and if I'm reading

Can this be changed to LPGLv3+? That'd solve the problem.
True, but it would have knock-on effects on all sorts of other clients
of libvirt. I'm re-adding the libvirt list for

You can define it by yourself: Basically you define
#if @BITSIZEOF_SIZE_T@ == 32
# define PRIuSIZE PRIu32
#endif
#if @BITSIZEOF_SIZE_T@ == 64
# define PRIuSIZE PRIu64

You _can_ use this. It will work as long as each of your program's data
structures is less than 4 GB large. Remember that size_t values get
larger than 4 GB only if you have a memory object
