In #19015 it's been suggested that we add some new compiler warnings to our build. Some of these, such as `-Wunreachable-code-loop-increment`, generate warnings. We'll likely want to fix these up if we're going to turn these warnings on.

```bash
init.cpp:969:5: warning: loop will run at most once (loop increment never executed) [-Wunreachable-code-loop-increment]
    for (const auto& arg : gArgs.GetUnsuitableSectionOnlyArgs()) {
    ^~~
1 warning generated.
```

If you want to build master, with `-Wunreachable-code-loop-increment`, you can use something like this:
```bash
./autogen.sh
./configure CXXFLAGS="-Wunreachable-code-loop-increment"
make check
```
signal(SIGPIPE, SIG_IGN);
#else
    SetConsoleCtrlHandler(consoleCtrlHandler, true);
#endif
    std::set_new_handler(new_handler_terminate);
    return true;
}
bool AppInitParameterInteraction()
{
    const CChainParams& chainparams = Params();
    
    
    
    
    
    std::string network = gArgs.GetChainName();
    for (const auto& arg : gArgs.GetUnsuitableSectionOnlyArgs()) {
        return InitError(strprintf(_("Config setting for %s only applied on %s network when in [%s] section."), arg, network, network));
    }
    
    for (const auto& section : gArgs.GetUnrecognizedSections()) {
        InitWarning(strprintf(Untranslated("%s:%i ") + _("Section [%s] is not recognized."), section.m_file, section.m_line, section.m_name));
    }
    if (!fs::is_directory(GetBlocksDir())) {
        return InitError(strprintf(_("Specified blocks directory \"%s\" does not exist."), gArgs.GetArg("-blocksdir", "")));
    }
    
    std::string blockfilterindex_value = gArgs.GetArg("-blockfilterindex", DEFAULT_BLOCKFILTERINDEX);
    if (blockfilterindex_value == "" || blockfilterindex_value == "1") {
        g_enabled_filter_types = AllBlockFilterTypes();
