Fwd: NSCalendar behavior

[Alessandro Sangiuliano]

Hello, I've a different behavior of NSCalendar that makes my little App 
to work on OS X 10.10, 10.6.8, but not on GNUstep.

I wrote the App on 10.10, then ported on 10.6.8 to make compatible 
GNUstep nibs/xibs, then ported on GNUstep.

The problem seems to come from the line 59 in AppDelegate.m, when trying 
to calculate an NSRange:

NSRange range = [gregorian rangeOfUnit:NSDayCalendarUnit 
inUnit:NSMonthCalendarUnit forDate: [gregorian 
dateFromComponents:components]];
monthDays = range.length;
NSLog(@"Numbers of Days %ld", monthDays);

 From the NSLog I can see that monthDays is "0", insted on OS X is 28 
(for february, 31 for Jan, and so on). What I wrong?

You can look the code on github: 
https://github.com/AlessandroSangiuliano/Calendar In the OSX directory 
there is the OS X 10.10 version of the App.

 Best Regards,
Alex
