On Windows, std::tmpfile() returns NULL with errno 22 when %TEMP%
contains a character outside the ANSI code page, where GetTempPathA
returns '?' in its place. Fifteen tests that capture output through it
aborted. TemporaryFile::Open() opens a unique delete-on-close file under
temp_directory_path() with _wfopen; other hosts keep std::tmpfile().

The PS5 3.20 export inventory lists _err, _warn and _getprogname in
libSceLibcInternal next to err, warn and getprogname, with the NIDs
UhKI6z9WWuo, XQFE8Y58WZM and iI6kGxgXzcU. In FreeBSD 11.4 libc the
underscore names are the definitions and the public names are weak
references to them (lib/libc/gen/err.c, lib/libc/gen/getprogname.c),
and libthr interposes none of them, so each pair is one function.
_err and _warn now hand their arguments to verr and vwarn, which use
errno at the call as err and warn do; _getprogname returns
getprogname(). The debt file records that the console's module was not
read.
guest_err checks the _warn and _err text for errno 13 with a formatted
message, that _err passes its status to the err_set_exit hook, and that
_warn without a format returns without calling the hook.
guest_program_name checks that _getprogname returns the current
__progname pointer.

The guest is LP64, so vwarnx consumes a full 64-bit slot for %ld. On LLP64 hosts (Windows) the 123456789L argument is only 32 bits wide and leaves the upper half of that slot undefined, so the check saw garbage in the high bits.
