------------------ Additional Follow-up Comments ----------------------------
Actually, the length of the buffer depends on the value of the radix. I've 
added the following to the dox itoa and related functions (both HEAD and 1.0 
branch):



Note:



The minimal size of the buffer s depends on the choice of radix. For example, 
if the radix is 2 (binary), you need to supply a buffer with a minimal length 
of 8 * sizeof (long int) + 1 characters, i.e. one character for each bit plus 
one for the string terminator. Using a larger radix will require a smaller 
minimal buffer size.



Warning:



If the buffer is too small, you risk a buffer overflow.

Summary:  Things missing from docs in avr-libc

Original Submission:  __lpm_inline is in the avr-libc FAQ (Why do all my 
"foo...bar" strings eat up the SRAM?), but is not in the "MODULES" section 
anywhere i've noticed.



itoa() and related docs don't say how long a string should be to prevent a 
memory over-run. I'd guess 7 (-32767
