  59 # header files are not found on the target system.  This will mean for
  60 # example, that xattr, acl and ldap headers must be installed for the
  61 # default build to complete.  The configure system will check for these
  62 # headers, and the error message will indicate the option (such as
  63 # --without-acl-support) that can be specified to skip this requirement.

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