No -fnowarn-missing-signature

[nobody]

On p. 53 the manual says (in the description of
"-Wall"):

 To turn off any warning, simply give the corresponding
-fno-warn-... option on the command line.

One of the options is  -fwarn-missing-signatures (p.
54).  Yet the compiler produces an error message:

 > ghc --make -odir ../ghc -hidir ../ghc
testDeclarationsMain.hs -o testDeclarations -Wall
-fnowarn-missing-signatures
  ghc-5.02.1: unrecognised flag:
-fnowarn-missing-signatures

The correct spelling of the option is -fno-warn-missing-
signatures.  The documentation and the implementation are 
both ok, as far as I can tell.
