   It does not.  C (up to C17) requires INT_MIN to be -32767 or lower,   
   and INT_MAX to be +32767 or higher.  (C23 changes the requirement   
   for INT_MIN from -32767 to -32768, and mandates 2's-complement for   
   signed integer types.)

   I have cc65 on my Ubuntu system.  Here's how I demonstrated the same   
   thing (that sizeof (int) is 2):   
      
   $ cat c.c   
   int SIZEOF_INT = sizeof (int);   
   $ cc65 c.c   
   $ cat c.s
