Details:

According to Apple's documentation this method "Returns nil if a connection
could not be created or if the download fails." The GNUstep implementation,
however, also returns nil from this method when the body of the web server
response is empty. It should return an empty NSData object instead.
Test case is attached. The attached, simple web server responds 204 No Content
to every GET request. When compiled with GNUstep the test program prints
127.0.0.1 - - [2013-01-08 10:31:38 +0100] "GET / HTTP/1.1" - "HTTP/1.1 204 No
Content"
2013-01-08 10:31:38.719 test[89837] data = (null)
When compiled with Cocoa, the test program prints:
127.0.0.1 - - [2013-01-08 10:32:55 +0100] "GET / HTTP/1.1" "test-Cocoa
(unknown version) CFNetwork/454.12.4 Darwin/10.8.0 (i386) (iMac5%2C1)"
"HTTP/1.1 204 No Content"
2013-01-08 10:32:55.592 test-Cocoa[89858:903] data = <>
