this looks like something I recall fixing, but don't see it immediately
in the change-log.

offhand: type_names is part of TERMINAL; as part of my ongoing changes,
I cloned TERMINAL as TERMINAL2 for the "real" information and generate
the content of TERMINAL from that.

With MinGW, you have to use an option (--enable-term-driver) which uses
different code in which it seems I overlooked the fix mentioned above.

with NCURSES_TRACE=1, you'd see nothing:
#define TRACE_TIMES     0x0001  /* trace user and system times of updates */

since that's used only in doupdate (executed when repainting the screen)

and that would be "trace", not "trace.log"
