I'd suggest to use C++ here:
Suggestion:

    const tstring psnArgPrefix = "-psn_";
    for (int i = progNameMode == ExcludeProgramName ? 1 : 0; i < argc; i++) {
        const tstring arg = argv[i];
        if (!tstrings::startsWith(arg, psnArgPrefix)) {
            result.push_back(arg);
        }
    }
