Agreed. This is the same with AX macros in configure.ac.

Not sure what you call run-time flags here. If you mean CFLAGS in the 
environment calling configure, I agree. Modifying configure.ac and 
calling make or compile will reuse the original CFLAGS the first time 
you run configure, unless you call configure explicitly. But the the 
CFLAGS added via configure.ac are kept in both cases. There is no issue 
here.
