String.toCharArray() and String.getBtytes are not const

What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?

What version of the Arduino software are you using? On what operating
system?  Which Arduino board are you using?

Please provide any additional information below.

[Apologies for the initial report - trying again...!]

Even though the implementation of String.toCharArray() and String.getBytes() 
return a copy of the internal buffer they are non-const, which means that 
rather than being able to write code such as:

  const String s("A string");
  char charArray[9];
  s.toCharArray(charArray, 9);

You have to cast away the const-ness (which is a bit messy):

  const String s("A string");
  char charArray[9];
  ((String)s).toCharArray(charArray, 9);

Both functions could be made const without breaking existing calling code and 
simplifying usage in this scenario.

I see that this change has already gone into the 1.0 new-extension branch as a 
result of the String class changes.

I know it's been a while.. perhaps you remember this?
did you ever get the string to work?

see error in comment

Thank you!

my code:

//from SerialEvent
const String g("geiger");
String inputString = "g";         // a string to hold incoming data
  char charArray[80];
  ((String)g).toCharArray(charArray, 80);   // error: expected constructor, destructor, or type conversion before 'g'

  boolean stringComplete = false;  // whether the string is complete

void setup()
{
  delay(1000);
  Ethernet.begin(mac, ip);
  // Ethernet.begin(mac);
  Serial.begin(9600);
//  String::toCharArray()  //testing
  inputString.reserve(200); //(200
//  inputString.toCharArray(g, 80);
  if (twitter.post(charArray))
  {

This has been fixed in Arduino 1.0.

Thank you!

how has it been fixed?
((String)g).toCharArray(charArray, 80)
gives errors no matter how i phrase it
