* Expand test suite.
BUGS:
-
-NOTE: in handle_merge_targets, 'all' handling is still wrong wrt
-subdirs. 'install' should always depend on "local all", whether 'all'
-or 'all-am'. Actually, something perplexing is going on. Why does
-"make install" in automake cause the recursion to happen twice??
-ANSWER: install-binSCRIPTS depends on 'all'. How to fix??
+* if config.h changes, recursive builds will not run even though they should.
+ all should depend on config.h and Makefile
Check all require_file errors to see if any should reference a line in
Makefile.am or configure.in.
