Hmm, this is quite odd. There's no such problem on Linux but I tried testing
on Windows and I now see what you mean. There seems to be a string-length
problem with [s]printf on Windows; I'll investigate.
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.
