  10: **	IIerror -- std. equel error reporting routine.
  11: **
  12: **		IIerror is called either directly by a
  13: **		routine detecting an error or by
  14: **		IIrdpipe where INGRES returns an error.
  15: **
  16: **		In the case of an appropriate error, IIerrflag is set to
  17: **		prevent the reading of the ovqp data pipe. This happens
  18: **		on errors that happen during retrieves to C vars.
  19: **
  20: **		Errno is the error number: 1??? is an equel error
  21: **		others are Ingres errors.
  22: **
  23: **		Argc and argv are structured as in Unix main program calls.
  24: **
  25: **		The error is printed if the call (*IIprint_err)()
  26: **		returns > 0. Otherwise no error message is printed.
  27: **		The error message that is printed is the one corresponding
  28: **		to the number returned by (*IIprint_err)().
