1. The error message is inaccurate; it doesn't actually call mkstemp()
on Windows, but mktemp().

2. The directory used for temporary files is controlled by the
STREAM_DIR= option (renamed to stream_dir= in 7.0). /var/tmp is just
the default setting.

3. The default value of /var/tmp is inappropriate for Windows. It
should probably use the TMP or TEMP environment variables. There
probably won't be a specific directory which will be writable by all
users.
