Alternatively, you can bootstrap by keeping term/x-win.el from being
preloaded in loadup.el during the bootstrap stage.  I think this will
decrease the optimal size of STATIC_HEAP_SIZE in sheap.c for Cygwin.

I still don't understand why term/*-win.el are changed to be preloaded
at the multi-tty merger.  If it was necessary for multi-tty, it might
cause some problems on CANNOT_DUMP platforms.  If not, then it was
really a bad idea (at least unfair) to slip such changes into the
unrelated event, i.e., the multi-tty merger.
