[Freeciv-Dev] CVS HEAD + mingw32 + gtk2 + SDL_mixer buglets

["Per I. Mathisen" <per@xxxxxxxxxxx>]

Good news: Current cvs does not flicker and speed is much better. Iso mode
is still slower, but not by much, and it is now usable.

Bad news: Using SDL_mixer slows unit movement down again to a crawl (but
better than it used to be). Goto crashes client (known problem?). Windows
not related to freeciv sometimes pop to the forefront when you close a
freeciv popup window - VERY annoying, no idea why. Vasco?

(I haven't tried the gtk2 client in S1_14 yet. Will do later.)
