[R] Increasing Max Vector Length

I'm looking at doing some really large linear algebra problems. I
followed the helpful instructions in the back of the installation
guide for rather aggressive compilation options on 64-bit
Solaris. Happily, I can address more than 6GB of RAM at once in R, so
I the 64 bit part works fine. With the Sun Performance libraries, R is
also very fast.

One thing that still bugs me is the maximum vector length, which
apparently is 268435455. Can I increase this? 32 bit SPlus has the
same limitations, but Fortran, C and 32 bit Matlab do not, so it's not
a machine thing, I believe.

Thanks for any help,
