GTK+ 2.2.1 build problems

["Brendan E. Conboy" <conboy marmail ed ray com>]

	I have been trying to build gtk+ 2.2.1 for a couple days now. At first
this same error was happening in the demos sub directory and after re-building
zlib with a .a extension I now get the error in the gtk/stock-icons dir:
