Use (#_GetCIcon NNN) instead of (#_getresource "cicn" NNN). Don't
#_DetachResource afterwards. When you're done with the icon,
use #_DisposeCIcon to get rid of it

:cicn is the same as "CICN" as an OSTYPE. When a symbol is interpreted
as an ostype, it's symbol-name is used. The reader upcases symbol names.
:|cicn| is the same as "cicn" since the vertical bars cause the reader
to not mess with case.
