Yes (assuming it works: that remains to be seen).  But: (a) I'd like
to hear Paul's opinion on this solution, since he is the one who
routinely imports Gnulib into Emacs; and (b) I'd like to see if
setting gl_cv_func_vasprintf_posix=yes in mingw-cfg.site (in addition
to ac_cv_func_vasprintf, if needed) will disable the compilation of
the *printf modules and solve the problem in a way that is simple and
doesn't require introduction of any new infrastructure into Emacs.
