I looked at it briefly a while ago and ran into a number of problems due 
to the fact that newlib required some macros that were taken away plus 
there were a number of other backward compatibility issues.  At the time 
I didn't see any compelling reason to make the switch.

I have just started relooking at it today.  I have gotten through a 
number of issues so far.  I still have to remove the annoying warnings 
about AC_CONFIG_SUBDIRS using a literal in the machine/OS-specific 
directories.  We configure the name of the machine directory and sys 
directory once at the top-level.  This name corresponds to 
subdirectories of lower directories which we conditionally configure 
using the names specified above.  It used to be nice and simple.
