	cygwin         : ChangeLog environ.cc environ.h 

Log message:
	* environ.h (win_env::immediate): Declare new field.
	(win_env::operator = ): Declare new operator.
	(win_env::reset): Declare new function.
	(win_env::~win_env): Declare new destructor.
	(getwinenv): Add optional third argument to declaration.
	* environ.cc (conv_envvars): Accommodate immediate field.
	(win_env::operator =): Define new operator.
	(win_env::~win_env): Define new destructor.
	(win_env::add_cache): Add value to environment immediately if "immediate" is
	set.
	(getwinenv): Accept optional third argument which will be used to store
	"cached" values to avoid overwriting real cache.
	(spenv::force): Declare new field.
	(spenvs): Accommodate force field.  Add "PATH=" with force set to true.
	(spenv::retrieve): Avoid duping anything if we're not building an envblock.
	(build_env): Ditto.  Use size of potentially constructed new environment block
	to determine if we need to create an environment block.  Pass getwinenv
	temporary storage to avoid inappropriately overwriting the environment cache.
