Even with that, don't we need first to move the automake process
currently done on ./Makefile.am to another file? Like let's say
Makefile.global.am, which contains all the variables set by automake.
Then we create a new file ./Makefile at the root folder that includes
Makefile.global. Something similar should be done with test/Makefile
(inclusion of ./Makefile.global) and it would be able to use the
values of CFLAGS, CDFLAGS and even PG_CONFIG that configure has set.
Thoughts?
