config.h is probably getting touched.

I call this a feature.  There have been several times I've made a change 
to the library where the library compiles but the examples don't.  If 
the examples don't build by default, I'll catch these problems later in 
the cycle.

Why is this a problem?  Is it just the extra time it takes?

That will do what you want.  But it won't do what _I_ want.  :)

All automake lets you do is append local rules to the end of the 'all' 
target processing, with an all-local rule.  You can't completely take 
over the target.
