BTW, it looks to me like you are actually compiling a more recent
version of Mercury, from the main branch of our CVS repository, rather
than the version-0_10_y branch (which is that branch that we used for
0.10 and 0.10.1).

The following patch will fix the symptom.

But I don't think it addresses the cause.  The cause is that for some
reason that I don't understand, the symbols in runtime/mercury_bootstrap.h
are not being defined.
