8884 globals_of_w32fns is used to initialize those global variables that
8885 must always be initialized on startup even when the global variable
8886 initialized is non zero (see the function main in emacs.c).
8887 globals_of_w32fns is called from syms_of_w32fns when the global
8888 variable initialized is 0 and directly from main when initialized
