The 'vasnprintf-posix' and 'vasprintf' modules together are not sufficient:
On a platform where vasprintf() exists but does not support %zu, gnulib will
arrange for vasnprintf() to be compiled and to support %zu but will not do
anything about %zu in vasprintf(). Whereas if you ask for the 'vasprintf-posix'
module, gnulib will arrange for vasprintf() to support %zu (which normally
will make it use vasnprintf(), but that's just an implementation detail).
