	* std/complext.h: Lose injection decls.
	* std/fcomplex.h: Likewise.
	* std/dcomplex.h: Likewise.
	* std/ldcomplex.h: Likewise.

Sat Sep 27 16:47:35 1997  Mark Mitchell  <mmitchell@usa.net>

	* std/complext.h: Declare templates before making them
	friends.  Use new friend <> syntax.
	* std/complext.cc: Don't rely on guiding declarations.
	* std/fcomplex.h: Use new friend <> syntax.
	* std/dcomplex.h: Likewise.
	* std/ldcomplex.h: Likewise.
