 I would love that.  I admin some bioinformatics clusters, and some
phylogenetics (tree-of-life reconstruction) programs use tree data
structures full of pointers that, with gcc-3.3, are faster in 32bit mode
than 64bit mode.  (It would really kick ass if AMD64 had a mode with the
extra registers, but 32bit pointers.  Then pointer-heavy data structures
would be faster.)  Anyway, being able to easily compile in 32 or 64bit and
benchmark would be very useful.  Also, I wouldn't have to statically link
64bit binaries that are faster in 64bit mode, and users wouldn't have to
deal with the chroot.  (not that it's much trouble with dchroot :)

 So, for me (and my ~dozen users) at least, this really would be useful.  If
you can't get it into sarge, I don't mind tracking unstable for some
packages on the cluster (it's not quite what some would call a "production"
system).  It would rock to have it in sarge :)
