! Fortran syntax considers signed int literals in complex literals
! to be a distinct production, not an application of unary +/- to
! an unsigned int literal, so they're used here to test overflow
! on signed int literal constants.  The literals are tested here
! as part of expressions that name resolution must analyze.
