That's interesting, I remember grabbing the pre-packaged one from the link in the wiki (that includes all the libraries), having issues, and then being told the issues were from an old, out-dated MinGW compiler that actually came from that zip-file (not using anything from the codeblocks website at all).
Hold on a sec while I check something...
Hmmmm, I see the link is dated late in 2007 from the beta installer page - I don't know if that's been updated or not - Oh, well, if it works now it works now - I suppose I might have simply been doing something wrong before, or I'm simply incorrect and imagining things in the first place, in which case I apologize.
Anyways, regarding the original issue, I'd suggest using an SVN copy or the more recent beta installer, not the one from March.
Still, that's strange what happened before with that zipped package... Hmmmm..... Oh well, If I was wrong and it works, I'm sorry. If I had more time I'd double check it, but right now I have some other things going on today.
