Well, <> is what the Autobook suggests; it won't make any difference 
for the decoders, though - they won't find config.h with "" in the 
user path anyway, since userpath means: same directory as source file 
or below; but config.h is one dir *up*. But our CPPFLAGS start with 
-I$(top_srcdir), guranteeing that our config.h is found immediatly.

Installing autoheader generated config.h files is a serious bug, but 
sadly, many apps do it :/ In fact, good that you remind me, I am not 
100% sure we don't (I didn't explicitly tell it to, of course, but 
checking that would be a good idea anyway).

Well, automake sadly has some serious limitation because it uses 
recursive make (like many bigger packages), which means that 
dependencies can't be resolved right.... you must make sure that the 
test app is built *after* the library. Try a make clean; make with 
your change, if it works, then it should be fine.
