In mingw's <stdio.h>.  But we can't do that.

vfprintf is NOT being provided by gnulib, so it does NOT understand %zu
or %llu.  Yet we use it with %zu.

So the only real solution is to use virAsprintf (which _does_ understand
%zu, thanks to gnulib) and make vshDebug go through an intermediate
buffer, then use fputs on that string, rather than relying directly on
the unsanitized vfprintf.  Patch coming up shortly.

Yep, I can fix that one in gnulib; I'll have a counterpart patch to bump
.gnulib to the latest once I've got it done.

Probably the same category of gnulib fix.

So I fixed the non-blocking pipe issues that broke 0.9.0 virsh
out-of-the-box?  Good to hear.
