This is the case in the current commit. I was trying to implement this with SmallSet and const char* to use the overload you mentioned, Jim, but I was having trouble with it, specially because I needed to hard code a 'max number of languages'. So I used the overload that takes a std::vector<std::string>. Let me know if that's not good. 

```cpp
case 'm': // Stop at user entry point
  {
    TargetSP target_sp =
        execution_context ? execution_context->GetTargetSP() : TargetSP();
    ModuleSP main_module_sp = target_sp->GetExecutableModule();
    FileSpecList shared_lib_filter;
    shared_lib_filter.Append(main_module_sp->GetFileSpec());
    std::vector<std::string> entryPointNames;
    for (LanguageType lang_type : Language::GetSupportedLanguages()) {
      Language *lang = Language::FindPlugin(lang_type);
      if (lang) {
        std::string entryPointName = lang->GetUserEntryPointName();
        if (!entryPointName.empty()) {
          entryPointNames.push_back(entryPointName);
        }
      }
    }
    BreakpointSP bp_sp = target_sp->CreateBreakpoint(
        /*containingModules=*/&shared_lib_filter,
        /*containingSourceFiles=*/nullptr, 
        /*func_names=*/entryPointNames,
        /*func_name_type_mask=*/eFunctionNameTypeFull,
        /*language=*/eLanguageTypeUnknown,
        /*offset=*/0, /*skip_prologue=*/eLazyBoolNo, /*internal=*/false,
        /*hardware=*/false);
    if (!bp_sp)
      error.SetErrorString("Breakpoint creation failed.\n");
    bp_sp->SetOneShot(true);
    break;
  }
```
