Difference between GCC 2.95 and GCC3.1

[Ravindra]

While moving from GCC 2.95 to GCC 3.1, we observed a problem when special characters(like - or :) were part of the Value in a dictionary.

 

In GCC 2.95 the following program prints {EX = "-16";}, where as in GCC3.1 prints it as {EX = -16;}

Because of the missing of double quotes in GCC3.1, unarchiving the archived objects at client side is failing.

#import <Foundation/Foundation.h>

int main (int argc, const char *argv[])

{

    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    NSMutableDictionary *thePlist = [NSMutableDictionary dictionary];

    [thePlist setObject:@"-16" forKey:@"EX"];

    NSLog(@"The Plist is %@",thePlist);

    [pool release];

    exit(0); // insure the process exit status is 0

}

We observed that setQuotables in NSString.m was changed from

 

 s = [[NSCharacterSet characterSetWithCharactersInString:           @"0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz$./_"] mutableCopy];   -- in GCC 2.95

 

to        s = [[NSCharacterSet characterSetWithCharactersInString:@"0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"
 @"abcdefghijklmnopqrstuvwxyz!#$%&*+-./:?@|~_^"] mutableCopy];  -- in GCC 3.1

 

If there is any specific reason behind this change, please let us know.
