But it doesn't matter since makefiles use `am/guilec', which doesn't do
this, does it?  (I did a "make clean && make check" before committing.)

I agree with Neil: it will work for you(tm), but we can't tell whether
it'll work on, say, hppa*-hpux* with HP's compiler.  So we need this
sort of hack.  Another hack would be to "(debug-set! stack 0)" when
building the compiler (assuming the compiler code is "sane" in terms of
stack usage), and maybe even when running tests.

Before the compiler is compiled, we can't avoid the evaluator, can we?

Thanks,
