Tested x86_64-linux. I am unable to test this on Cygwin myself. Testing
and reviews invited.

Cygwin should use std::fwrite, not WriteConsoleW. And the -lstdc++exp
library is only needed when running the tests on *-*-mingw*.
libstdc++-v3/ChangeLog:
* include/std/ostream (vprint_unicode) [__CYGWIN__]: Use POSIX
code path for Cygwin instead of Windows.
* include/std/print (vprint_unicode) [__CYGWIN__]: Likewise.
* testsuite/27_io/basic_ostream/print/1.cc: Only add -lstdc++exp
for *-*-mingw* targets.
* testsuite/27_io/print/1.cc: Likewise.
