Patch has been committed with the following changes:

putchar.c has been moved to libc/machine/xc16x and its prototype has 
been changed to accept an int rather than a char, per ANSI.

puts.c has also been moved libc/machine/xc16x.

You should understand that the shared putchar macro in stdio.h will get 
invoked by any user including stdio.h unless they surround the function 
call with parentheses or #undef the macro.  It calls putc() which 
eventually will end up using your write syscall in libgloss.  I'm not 
sure why you chose to override this particular function by itself other 
than a possible performance improvement or experiment, but be aware of 
the previous information.  If it was only meant as an experiment, feel 
free to request it being removed.

I regenerated the autotool files locally.
