wxWidgets on Mac fail to work again

[Mojca M. <moj...@gm...>]

Hi,

just to let you know: gnuplot fails to work with wxWidgets 3.0.0-rc1
on Mac (it worked with 2.9.5). I filed a ticket and I hope that the
issue will be resolved before the official release of wxWidgets 3.0.0.
I strongly suspect one specific commit (which kind-of-solved another
problem I had) might be the culprit, but I didn't test anything yet.

Someone mentioned a workaround: to move the Mac hack from within
wxtApp::OnInit() to some place before that, but I didn't test if that
has any influence and it makes most sense to wait for a response from
wxWidgets developers. (There is a chance that gnuplot will need a
slight modification.)

I first saw a bug report from a user on Mavericks [10.9] (where it
crashes), but I'm kind-of-able to reproduce the problem on Lion [10.7]
where it simply fails to initialize.

Luckily gnuplot still supports enough other terminals (where MacPorts
doesn't yet support Qt 5 and Qt 4 doesn't compile on 10.9, AquaTerm
has limited functionality and Apple is slowly phasing out X11).
