[3/4] user32/cursoricon.c: Multiple Fixes/Improvements for DrawIconEx

[Juan Lang]

Hi Wilfried, minor comment on this patch:

                 hBitTemp = SelectObject( hMemDC, hXorBits );
+
+                UINT bltFlag = 0;

C89 doesn't allow you to mix code and declarations like this.  You'll
have to declare bltFlag at the top of the block.
