Hack

After working around a few issues, wordpad crashes inside _initterm. Native
msvcrt doesn't help.

You need wordpad.exe and wordpad.exe.mui from win7.

Then you'll need "winetricks mfc42".
Also will need native uiribbon and uxtheme.

Last, you'll need attached hack to work around bug 43670 and fix the issue this
bug is about.

The problem seems to be that the called function doesn't save esi, but gcc
assumes it is. At least, it works when manually saving esi, or changing the
code so that gcc doesn't use esi in the first place.
