Can't imagine why.  And why only for MS-DOS and Windows?  It is equally 
appropriate for any system.

The only reason I know of, for including ctype.h, is to inline calls to the 
family of character characterisation functions such as `isalpha', `isalnum',
`isupper', etc., using macro implementations.  I don't see any such calls in 
pipeline.c, so I think you are correct; it is not necessary.
