It is a very problem which I don't feel we can solve properly now.
CVS Automake should have some bits which help on this issue, but the
safest is definitely to run AC_PROG_CXX first.
No. This doesn't help at all (Cf. my initial hello.cc example, it applied 

Running AC_PROG_CC first sometimes helps, but it apparently doesn't always help. However, I am inclinded to consider this "pampering with symptoms" and not being an actual cure.

BTW: Meanwhile, after some considerations, I vote for using AC_CHECK_TOOL inside of the check for cpp and to fall back to /lib/cpp as last resort.
