No. This doesn't help at all (Cf. my initial hello.cc example, it applied 
AC_PROG_CXX only)


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.
