Is it correct to say that ethenol is an alcohol? IUPAC Gold Book defines alcohols as:


  Compounds in which a hydroxy group, $\ce{–OH}$, is attached to a
  saturated carbon atom $\ce{R3COH}$.


However, Wikipedia says that:


  Vinyl alcohol, also called ethenol (IUPAC name), is an alcohol.


Is Wikipedia wrong about this?

And if ethenol is not an alcohol, what would be the correct name for compounds in which an $\ce{–OH}$ group is attached to an unsaturated carbon atom?
The golden book states that ethenol is an alcohol: 


  Enols
  
  Alkenols; the term refers specifically to vinylic alcohols, which have the structure $\ce{HOCR'=CR2}$.


However, the modifier "vinylic" is rather important, so I would never omit it.
