The recent changes broke the mingw64 (64bit) and cygwin w32 builds of
emacs.

Cygwin and msys2 mingw64 headers from w32api have this in usp10.h:

  22  #if !defined (UNISCRIBE_OPENTYPE) && (_WIN32_WINNT >= 0x0600)
  23  #define UNISCRIBE_OPENTYPE 0x0100
  24  #endif

  67  #if UNISCRIBE_OPENTYPE >= 0x0100
  68  typedef ULONG OPENTYPE_TAG;
  69  #endif

This seems to fix the build:
