That broke build process (you couldn't even force specific version) on
Ubuntu Fiesty (and possibly Debian), as one can have more than one
wx-widgets version installed and default wouldn't be necessary the best
one.

In fact, Ubuntu Fiesty defaults to 2.6.x, and so the check used
in ./configure (wx-config --version) gives 2.6.3, where
(wx-config --version=2.8 --version) gives 2.8.1.

So I created really ugly patch (as am really I not into shell scripting, nor
m4 macros), to fix it, but it might not work with non-debian wx-config
versions, so please doublecheck/improve (strongly recommended ! :-).

Well, in fact all major-minor version checking magic might be probably
thrown away, as we are asking wx-config for specific versions anyway.

Ugly (but works-for-me) patch attached.
