Hi Markus,
I failed to build this file with i686-w64-mingw32-g++ 4.8.2, shipped
in Ubuntu 14.04.

gdb/unittests/scoped_fd-selftests.c:37:29: error: ‘mkstemp’ was not
declared in this scope
   int fd = mkstemp (filename);
                             ^
gdb/unittests/scoped_fd-selftests.c: In function ‘void
selftests::scoped_fd::test_release()’:
gdb/unittests/scoped_fd-selftests.c:56:29: error: ‘mkstemp’ was not
declared in this scope
   int fd = mkstemp (filename);
                             ^

There is no such error with i686-w64-mingw32-g++ 5.3.1.  Can we use
"open" instead?
