Some of the test suites use fprintf with format specifiers
that are not supported on Win32 and are not fixed by gnulib.
The mingw32 compiler also has trouble detecting ssize_t
correctly, complaining that 'ssize_t' does not match
'signed size_t' (which it expects for %zd). Force the
cast to size_t to avoid this problem
Nothing wrong with your libvirt patch, but I can't help wonder if this
is a bug in the gnulib replacement headers, where mingw lacks ssize_t
but gnulib defines it to the wrong type in comparison to size_t (that
is, since mingw64 has sizeof(size_t)==4, it is not obvious whether
size_t is 'unsigned long' or 'unsigned int', and if gnulib picked
'int'
for ssize_t but size_t is 'unsigned long', that would explain the
compiler warnings. Gnulib may need to be tweaked to help work around
this mingw situation.
