I have not been able to figure out what is happening yet, just that
something isn't working.

I've tried the tip of 'new-signals' and can't even get it to
bootstrap.  It prints out quite a few warnings like:

/home/davidb/wd/lisp/ecl/src/c/file.d:1784: warning: cast from pointer
to integer of different size

which looks like you might be assuming that 'int' is the same size as
a pointer, which it is not in x86_64.

If I break in the debugger in bootstrap, and it appears to be just
about to print "Internal or unrecoverable error in:

Lisp initialization error."

I can poke further if you have any other ideas.
