* win/Makefile.in: Subst DEPARG directly instead

	of relying on a variable. This will make Cygwin
	build faster since an extra exec will be avoided.
	* win/configure: Regen.
	* win/configure.in: Subst DEPARG.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Move AC_MSG_CHECKING
	after the AC_CHECK_PROG so that status messages do
	not get mixed together. Set DEPARG based on the
	results of the cygpath check so that we avoid using
	an extra exec when it is not needed. Use ac_cv_cygwin
	status flag instead of looking at the output of
	gcc -v, which works in the case where -mno-cygwin is
	set in the CFLAGS.
