(CodeSourcery) gcc link errors for hello world?

As usual, I must be missing something totally basic here...

#include "stdio.h"
int main()
{
    printf("hello world\n");
    return 0;
}

Link errors say the following functions are not found:

• _close
• _fstat
• _isatty
• _lseek
• _read
• _sbrk
• _write

Notes

1. The ultimate goal is to compile StarterWare's usb_bulk_dev example (not supported by CCS CGT?), so the target platform is ARM EABI (arm-none-eabi-gcc)
2. Linking with the flags "-lc -lgcc -lg" doesn't fix the link errors
3. CodeSourcery's libc.pdf (Chapter 12) says to write your own stub functions?  Is there no easier way?
4. Is (3) really how StarterWare does it? But then why are sbrk, etc. nowhere to be found in the source code?
5. Or, do gcc-compiled StarterWare programs not support printf at all??
