It has just dawned on me that the compilation failures quoted are occurring during 'dmake test' and not 'dmake' as I had assumed. (My mistake - it's pretty obvious that 'dmake test' is under way.)

Normally, by the time we get to 'dmake test', all compilation has been done - and it's uncommon to see compilation being carried out during the 'dmake test' stage. What module is it (in your original post) that you are trying to build ?

Cheers,
