Thanks; that made it worse, though, and it doesn't build:
.\apps\s_cb.c(731) : error C2027: use of undefined type 'in6_addr'
.\apps\s_cb.c(731) : see declaration of 'in6_addr'
(which somehow reminds me of a bug fixed a couple versions ago)
But I do think you are on to the underlying problem. I guess
opensslconf.h is modified (and others?!), as part of the configure
operation, but those changes are not effectively reflected in the
include/openssl because those are copies on windows, rather than
symlinks as on unix. Maybe a postconfig step should be added to update
those header files in that platform's config script.
