Hi Marek and all.

From setjmp.h (avr-libc-1.2.0 and early):

   #define _JBLEN 24
   typedef struct _jmp_buf { unsigned char _jb[_JBLEN + 1]; } jmp_buf[1];

What is the reason to reserve extra one byte in jmp_buf?
Functions setjmp/longjmp use only 24 bytes now.

By fixing bug #4101, I have exclude this extra byte.
