Then either the Linux manpage is deficient or the routine is broken.

 From a BSD man:

      The strcspn() function spans the initial part of the nul-terminated
      string s as long as the characters from s do not occur in string
      charset (it spans the complement of charset).

Or we have a problem of conflicting standards.  :-)
