Corinna Vinschen d2a88d9792 Throughout, drop unnecessary explicit includes of windows header files
included by default.
	* winlean.h: Add long comment to explain why we have to define certain
	symbols.
	(_NORMALIZE_): Define.
	(_WINNLS_): Drop definition and subsequent undef.
	(_WINNETWK_): Ditto.
	(_WINSVC_): Ditto.

in autoload.cc leads to "multiple definition" errors. The macros control
the declarations of symbols in the Mingw64 w32api headers. If they are
not defined, a DECLSPEC_IMPORT will be added to the symbol declarations.
This leads to a definition of the symbols in the sources using the
autoloaded symbols, which in turn clashes with the definition in the
w32api library exporting the symbols. */
