A few more things I'd like to understand are:

1) In what circumstances exactly would the configure script have to be re-run?

You run configure once to setup a particular build configuration. After it is run, you only need to run make for the build configuration. Rerunning configure on an already setup build configuration is not recommended. If you want to tweak something (like different flags to compilers and such, just edit the generated spec.gmk file.

2) Can you give examples of the kind of build changes that would be needed :- - when a small'ish change is made (eg adding a couple of new source files, or renaming or removing them)?

Adding/removing source files does not require a rerun of configure.

- when a new component is added, with both Java and native sources in new source directories

Adding an entire subdirectory of sources, more native source etc etc does not require a rerun of configure.

Configure does not care about source code layout except where the repositories are. It knows how to find/download compilers/linkers/tools and create a spec.gmk file with all the necessary variables that encode this information. (For example: CC,JDK_TOPDIR,OUTPUT_ROOT,ARCH etc etc)
