Aquí tienes el código: ;)

int comprobar_palabra(char *palabra) {
  if (palabra == NULL)
    return -1; // Error

    char *validas[9] = {
        "helpview.jpg\0", 
        "appInfo.json\0", 
        "keytrialkey\0", 
        "ezsubtitle.srt\0", 
        "ezsubtitle.srt\0", 
        "ezsubtitle.sim\0", 
        "ezsubtitle.ssa\0", 
        "ezsubtitle.cdg\0", 
        "time.txt\0"
    };

    int comparacion;
    char *extension;

    for (int i = 0; i < 9; i++) {
        // strcmp: 0 si son igual, diferente si no lo son (<0 o >0)
        comparacion = strcmp(palabra, validas[i]);
        if (comparacion == 0)
            return 0;   // Se acepta el fichero

        // Mueve el puntero hasta el ., así solo compara la extensión
        char *extension = strrchr(palabra, '.');
        comparacion = strcmp(extension, ".pem");

        if (extension != NULL && comparacion == 0) 
            return 0;
    }
    return 1;   // El fichero no es válido
}
