This is, again, odd ChangeLog formatting.  The wrapping is weird
and the indentation is off.

Anyway, shouldn't we be turning on _POSIX_THREADS in
newlib/libc/include/sys/features.h ?  It doesn't seem right to
be checking explicitly for both a generic case (_POSIX_THREADS)
and a system specific case (__CYGWIN__).  The _POSIX_THREADS
definition is there to control this, isn't it?
