Hmm, thanks for the info. I really thought the Debian guys had stopped
unilaterally breaking wxWidgets like that (downstream patching used to
cause other problems with Debian in years gone by). Reminds me of why
I prefer Redhat.

There are a lot of things that aren't documented in wxWidgets. If we
removed all of them from pgAdmin... well, we just couldn't.
Unfortunately we can't just copy them because the licences aren't
compatible.

Anyway, thanks again for the info - I guess we'll just check to see if
WX_ATTRIBUTE_PRINTF* is defined, and if so use that instead of
ATTRIBUTE_PRINTF*.
