I just tried your test with g++ (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2:

$> ./testvswprintf
this works, 1, 2, 3...
but the following does not:
ret: 1
buf: >T<
>T<
ret: 4
wcout: >THIS IS A TEST<

Looks quite the same, so itÂ’s not really a Cygwin-only problem.
My Ubuntu 11.04 is a bit dated already, so maybe you have a newer
Ubuntu version with a fixed swprintf?
