        PR fortran/43665
        * intrincic.texi (FGET, FGETC, FPUT, FPUTC, FSTAT, GETCWD, KILL,
        STAT): Show also syntax for the function version.
        * intrinsic.c (add_sym_1s_intent, add_sym_2s_intent,
         add_sym_3s_intent): Remove function.
        (add_sym_1s, add_sym_2s, add_sym_3s): Take always the intent
        as argument.
        (add_sym_2_intent): New function.
        (add_functions): Set intent for functions which modify
        the argument: fstat, fgetc, fget, hostnm, lstat, stat. Change
        argument name of hostnm from "a" to "c"
        (add_subroutines): Change add_sym_*s_intent to
        add_sym_*s and add intent to the add_sym_*s calls.
