Hi Christophe,
when I try and build a PharoVM from the Cog sources after merging this pull request I get the following error:
```../../platforms/iOS/vm/OSX/SqueakOSXApplication.m:76:37: error: no visible @interface for 'sqSqueakMainApplication' declares the selector 'setAboutWindow:' [gDelegateApp.squeakApplication setAboutWindow: [self keyWindow]]; ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~~~ 1 error generated.```
It's coming from this method:
```@implementation SqueakOSXApplication ... - (void)orderFrontStandardAboutPanel:(id)sender; { [super orderFrontStandardAboutPanel: sender]; [gDelegateApp.squeakApplication setAboutWindow: [self keyWindow]]; }```
