*+
*  Name:
*     AST_REXIT

*  Purpose:
*     Output a error message from a routine

*  Language:
*     Starlink Fortran

*  Invocation:
*     CALL AST_REXIT( RTN, STATUS )

*  Description:
*     Reports a standard error given a routine name so that error dumps
*     have a uniform neat appearance. Parameter system aborts are ignored.

*  Arguments:
*     RTN = CHARACTER*(*) (given)
*        The name of the routine reporting the error
*     STATUS = INTEGER (given)
*        The global status.
