I also passed much time trying to improve the integration and checks 
done in sqlite3.m4, but did not come to anything much better yet.
I'm wondering whether the check for <inttypes.h> and PRIu64 could not be 
changed to just:

AC_CHECK_DECLS([PRIu64],
   [AC_DEFINE([OVSQLITE_USE_DICTIONARY], 1,
              [Enable use of a dictionary with zlib if PRIu64 is 
available.])])

As a matter of fact, PRIu64 is only used for compressed ovsqlite 
overview data.  And we would then use OVSQLITE_USE_DICTIONARY instead of 
USE_DICTIONARY (unconditionally defined otherwise in ovsqlite-server.c).

Would it suit you?  Or did you have another idea in mind for 
USE_DICTIONARY and PRIu64 availability?
