	* win/tcl.m4 (SC_CONFIG_CFLAGS): Don't default to -O.
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Don't default to -O.
	CFLAGS gets set to "-O2" by default in top level
	configure. Adding "-O" here causes the "-O2" to be
	ignored, but only when the user types "make" within
	the tcl subdirectory. This caused some confusion.
	* win/configure: Rebuilt.
	* unix/configure: Rebuilt.

	* generic/tclEnv.c (TclUnsetEnv): Cast arg to unsigned.

	Import from latest tcl sources to fix a bug with
	"file copy"

	* win/tclWinFCmd.c (DoRenameFile, DoCopyFile, squelch_warnings):
	Re-implement inline ASM SEH handlers for gcc.
	The esp and ebp registers are now saved on the
	stack instead of in global variables so that
	the code is thread safe. Add additional checks
	when TCL_MEM_DEBUG is defined to be sure the
	values were recovered from the stack properly.
	Remove squelch_warnings functions and add
	a dummy call in the handler methods to squelch
	compiler warnings.
	* win/tclWinReg.c: Add casts to avoid compiler
	warning. Fix assignment in if expression bug.
