Hi Jerry:
The best source is svn. Let's take example 6 which is an easy one.
"svn log examples/c/x06c.c"
shows the key revision was 10908. So do an svn diff with the revision
just before that:
svn diff -x -w --revision 10907 examples/c/x06c.c
(where -x -w are important options which mean whitespace changes will be
ignored by svn diff). The following results are obtained by that command:
Index: examples/c/x06c.c

So those two extra loops should be a straightforward change to implement for
all instances of example 6 for all our non-C languages. Example 7 changes
should be similarly straightforward. Once 6 and 7 are knocked off the
remaining differences will look much more tractable.
