Yep, libwinpthreads was the problem.

It only affected the no-dependency version of Emacs which has other than
libXpm, no dependencies. Without -static it broke complaining about
libwinpthreads.

Nasty hack. Well worth checking whether it is still a problem (it comes
from msys2 and that's changed lots). And if it is, worth wondering
whether no-deps is still needed.
