ConfigurationNotChecked error with Cppcheck

I checked my program with cppcheck with the following command.

cppcheck --enable=all --inconclusive --xml-version=2 --output-file=getopt.c.txt -v getopt.c

It gives me some ConfigurationNotChecked erros. I searched online but don't know what it means. Some errors are below.

    <error id="ConfigurationNotChecked" severity="information" msg="Skipping configuration &apos;__STDC__=0;const&apos; since the value of &apos;const&apos; is unknown. Use -D if you want to check it. You can use -U to skip it explicitly." verbose="Skipping configuration &apos;__STDC__=0;const&apos; since the value of &apos;const&apos; is unknown. Use -D if you want to check it. You can use -U to skip it explicitly.">
        <location file="getopt.c" line="194" column="0"/>
    </error>
    <error id="ConfigurationNotChecked" severity="information" msg="Skipping configuration &apos;__STDC__=0;const&apos; since the value of &apos;const&apos; is unknown. Use -D if you want to check it. You can use -U to skip it explicitly." verbose="Skipping configuration &apos;__STDC__=0;const&apos; since the value of &apos;const&apos; is unknown. Use -D if you want to check it. You can use -U to skip it explicitly.">
        <location file="getopt.c" line="208" column="0"/>
    </error>

        <location file="getopt.c" line="317" column="0"/>
    </error>

It says use -D to check it. How can I use it with my command that i wrote above. I want to get information about what this error is. Also does my cppcheck command giving me all the possible errors that it can find or am i missing some argument.

I am a Cppcheck developer. That is very weird. This sounds like a Cppcheck bug.

You should not use -D in this case.

Ideally I would like that you create a short code example that reproduce the problem. Maybe you can extract some code in getopt.c around line 190 and see if you still get such information message.

The manpage describes this

       -D<id>
           By default Cppcheck checks all configurations. Use -D to limit the checking. When -D is used the checking is limited to the given configuration. Example: -DDEBUG=1
           -D__cplusplus
