[Rd] packages with DLLs under 2.12.0

[Peter Ehlers]

I realize that R-core must be busy with the imminent release of
2.11.0, so please consider this not urgent.

The NEWS file for 2.12.0 (Windows-specific) says, in part:

   For now, 32-bit packages with compiled code built under
   2.{10,11}.x can be used, but this will be disabled before
   release.

For me, this doesn't work without a tweak. For example,

 > library(mvtnorm)
#Error: package 'mvtnorm' is not installed for 'arch=i386'

I tested a few (6 or 7) other randomly selected packages
(bitops, igraph, ...) before wising up and looking at the
recommended and automatically installed packages like
lattice, etc. I see that the 'libs' folder now has an
'i386' subfolder where the DDLs reside.

Making that change by hand fixes the 'problem'.
