  78 # example, that xattr, acl and ldap headers must be installed for the
  79 # default build to complete.  The configure system will check for these
  80 # headers, and the error message will indicate the option (such as
  81 # --without-acl-support) that can be specified to skip this requirement.

  84 # functional packages, while allowing those on systems truly without these
  85 # facilities to continue to build Samba after careful consideration.
