Just a word of warning. The current Visual C version in CVS is most likely
broken. I hope to get that fixed soon.
You should always give the version you are using, because that way we are
able to see if some bug was fixed.
Kieran is right, that this seems to be a problem with you visual c++
version. Which one are you using? I tested with VC++6 SP4 (and a bit with
SP5).
