Indeed, I simply made all bare-metal targets use newlib-stdint.h as a 
default, but since AVR has its own libc it seems more appropriate to put 
the defines in avr-stdint.h or avr.h and not use newlib-stdint.h.  (And 
the point of having separate headers such as newlib-stdint.h is that there 
may not otherwise be a header shared between all relevant targets.  If all 
AVR targets use avr-libc, putting the defines in avr.h makes sense, but if 
avr-rtems is using newlib like other RTEMS targets then you probably want 
a separate header only for AVR targets using avr-libc.)
