In which case I think I have misunderstood how the build system works. I
presumed that the dependencies would be tested before they were used. However
you are suggesting that they are not tested until the compiler is tested.

I have cut "make check install" down to "make install" in my build script and
it does indeed run to completion. Of course now I have an untested compiler
which is a little alarming but it helps identify the source of the problem.

Apologies for the wild goose chase.
