I'm glad you exposed this problem. Gretl's "printf" and "sprintf" are
implemented internally using the C-library function vsnprintf and it
turns out we were missing something: on Windows vsnprintf doesn't
conform to the ISO C standard by default; you have to define a special
macro to get standard-conforming behavior. We're now doing that (in
git and snapshots). So the workaround I described is no longer needed.
