// This file is included by <cstdio> and the like that are used from other
// libc++ headers that are wrapped by ktl. This file exists to preempt those
// inclusions so that libc++'s <wchar.h> wrapper header won't be used, since
// it's not compatible with the kernel environment. However, other libc++
// headers also use `#include_next <wchar.h>` to get to "the system libc"
// version of the header. To satisfy those, include-after/wchar.h provides the
// actual declarations needed from the standard C <wchar.h> API. So this
// header just defers to that one, but must exist separately in this directory
// so that it preempt's libc++'s wrapper. This can't itself use #include_next
// because that would reach libc++'s wrapper before the include-after file.
