At one point lookup switches (the ones that use bit-vectors IIRC)
didn't respect the --cross-compiling option.  (I think that has long
since been fixed.)

A 64-bit stage 1 compiler built using a 32-bit source distribution
bootstrap compiler would end up being broken.

I've always meant to check that things are working and remove
--no-smart-indexing from that list since *not* enabling means that MSVC
cannot compile the pre-generated .c files in the source distribution.
(At least I've always mean to check it everytime I remember that
we currently use --no-smart-indexing, which isn't often ...)

Cheers,
Julien.
