binutils warning fixes

[Alan Modra <amodra@bigpond.net.au>]

Fixes a number of warnings.  I guess the only thing that needs
explaining is why moving assert.h and time.h before getopt.h matters.
The reason is that include/getopt.h gives a getopt() a prototype if
__GNU_LIBRRY__ is defined, which we get via the system headers.  Which
I guess only kills the lack of prototype warning on systems using
glibc.  So I decided to also include unistd.h, which should provide
getopt() too.

binutils/
	* deflex.l (YY_NO_UNPUT): Define.
	* rclex.l (YY_NO_UNPUT): Define.
	* rcparse.y (null_unichar): New static var.
	(res_null_text): Use it rather than attempting to init from wchar_t.
	* windres.c <assert.h, time.h>: Include before getopt.h.
	Include config.h and unistd.h too.
