Update.
* misc/error.c (error): Handle wide oriented stderr stream correctly. * stdio-common/perror.c (perror): Implement according to standard. The stream orientation must not be changed if the stream was not oriented before the call. * stdio-common/Makefile (tests): Add tst-perror. * stdio-common/tst-perror.c: New file. See ChangeLog.12 for earlier changes.
