If I run the individual perl tests under gdb, the nature of the failure
becomes a bit more clear.

op/cmp.t:

  (gdb) file ./perl
  Reading symbols from ./perl...(no debugging symbols found)...done.
  (gdb) set args op/cmp.t
  (gdb) run

Hmmm... that's not good.

op/numconvert.t:

All the others, with the exception of the pragma/locale.t test,
experience the same type of errors:

I did notice the the `Configure' script did make allowances for the
absence of the "machine/ieeefp.h" include, and I'd have thought it would
be able to likewise work around the absence of IEEE fp, but maybe not.
There must be a way to reimplement infnan() and strtod() to work within
the framework of VAX fp.  How does Perl deal with this on Ultrix, or
even on VAX/VMS?
