- Declare 'tgoto' if not already declared in system header files. 


cmd-line-utils/libedit/el_term.h:
  Declare 'tgoto' if not already declared in system header files. Failing
  to declare it will cause the pointer returned to be truncated
  to 32-bit integer which is no a valid pointer - in most cases.
configure.in:
  Add check to see if 'tgoto' is declared in system header files
