lib/libc/stdio : fputwc.c
Log message:
When encoding fails in fputwc(3), set the error indicator as required
by POSIX and as FreeBSD, SunOS 10/11, and glibc also do it. Note
that an enquiry to the Austin Group led to the conclusion that this
change probably violates the C standard: C and POSIX unintentionally
conflict. But the POSIX behaviour makes more sense (easier to write
correct error handling code for it, and a lower risk that programs
miss errors) and is much more widespread, and the Austin Group
intends to approach the C committee in order to adjust the C standard.
See: http://austingroupbugs.net/view.php?id=1022
While here, do not set errno a second time, wcrtomb(3) already did that,
and it is required to do it by the standard.
OK millert@ and tedu@, and jca@ no longer objects
