early_init() calls decl_globals_init() which zeros out
a number structures:
ZERO(flags);
ZERO(iflags);
ZERO(a11y);
ZERO(disp);
ZERO(u);
ZERO(ubirthday);
ZERO(urealtime);
Setting values in any of those during startup prior to
the early_init() call was futile, and the values would
get overwritten.
Such was the case with the setting of iflags.colorcount
during Windows startup, so do it after early_init() has
been called.
