	ChangeLog 
Log Message:
	* win/tclWinPort.h: define USE_PUTENV_FOR_UNSET 1
	* generic/tclEnv.c (TclSetEnv, TclUnsetEnv): add
	USE_PUTENV_FOR_UNSET to existing USE_PUTENV define to account for
	various systems that have putenv(), but can't unset env vars with
	it.  Note difference between Windows and Linux for actually
	unsetting the env var (use of '=').
	Correct the resizing of the environ array.  We assume that we are
	in full ownership, but that's not correct.[Bug 979640]
