NSData -writeToFile:options:error: on MinGW

[Germán Arias]

After solve the problem with pthread and nanosleep (change the
parts/time.h header on MinGW and change config.h, in gnustep base, to
don't use nanosleep) I have other problem. The configure script now
defines HAVE_MKSTEMP to 1, used in -writeToFile:options:error: in
NSData. This part of code isn't mingw compatible, so I add some changes
(see attached patch). However a simple test fail. This program:

NSData *dat = [NSData dataWithContentsOfFile:
@"/MinGW/msys/home/German/src.txt"];

[dat writeToFile: @"c:/MinGW/msys/home/German/test.txt" atomically:
YES];

Always wrote the temporary file at current directory. So the NSData
object can't rename this later. What I'm doing wrong? Or is this a bug
on Base?

Thanks.
