+       * info/pcterm.c (kill): Move prototype from here...
+       * system.h: ...to here, conditioned by __MINGW32__.  This solves
+       compiler warnings in signals.c.
+       * info/pcterm.c (wcwidth): Make function's signature consistent
+       with Gnulib's prototype in gnulib/lib/wchar.h.
+
+       * info/session.c (w32_read): Provide prototype, to avoid compiler
+       warnings.
