    docs: fix: WARNING: Parsing of expression failed. Using fallback parser.
    
    For the future, we can use https://sphinx-fortran.readthedocs.io/ for
    Fortran functions which can have optional arguments. However, it's an
    additional dependency.
    
    Simplify the function declration.
    
    gcc/fortran/ChangeLog:
    
            * doc/gfortran/intrinsic-procedures/aint.rst: Simplify function
              declaration.
            * doc/gfortran/intrinsic-procedures/int.rst: Likewise.
            * doc/gfortran/intrinsic-procedures/anint.rst: Likewise.
            * doc/gfortran/intrinsic-procedures/char.rst: Likewise.
            * doc/gfortran/intrinsic-procedures/real.rst: Likewise.
