-[NSData writeToFile:atomically:] Bug introduced in 1.5.0

[Roland Schwingel]

Hi....

Im am still migrating sources... And I found I bug which was
(when diffing with base-1.4.0) introduced in base-1.5.0.

On Windows NSDatas -writeToFile:<path> atomically:YES is no longer working.
After creating the file it tries to rename() new File to old File. But 
it can't because
old file is still present....

If you go to line 907: you will find this:

   if ([mgr fileExistsAtPath: path])
   {
     att = [[mgr fileAttributesAtPath: path
                 traverseLink: YES] mutableCopy];
     IF_NO_GC(TEST_AUTORELEASE(att));
   }

In 1.4.0 the source looked like this:

    if ([mgr fileExistsAtPath: path])
   {
     att = [[mgr fileAttributesAtPath: path
                 traverseLink: YES] mutableCopy];
     IF_NO_GC(TEST_AUTORELEASE(att));
     [mgr removeFileAtPath: path handler: nil];
   }

mgr is declared previously. And indeed with 1.5.0 I am getting an 
errormessage regarding this problem to be
not able to rename the file.

Greetings,

Roland
