Real quick analysis of December's via "grep Subject" and wc:

Total: 			1020
version.c Updates:	 176
gnatvsn.ads Updates:	 124

So 300 are based upon an automated daily update of the version string.

There are 500 unique subject lines in the December log.  This is not
a 100% accurate reflection of unique modifications because the 
subject lines are truncated at about 64 characters and many start 
with the same string "Subject: gcc/gcc ChangeLog " so there isn't much
room for being unique based upon files in a change set.

This is 5 minutes of looking and my point is just to be careful 
looking at these.  I agree that there are probably a fair number of
changes but gcc is a LARGE body of source code so I would expect
changes.  Besides the compiler, there are test suites, documentation,
run-time libraries, and build support tools that support a variety
of host and target environments.  

The large number of host and target combinations means that it is
probably just a fact of life that what is an improvement to one 
target has a probability to break something else.
