I've added a page on the developer site on

        `Resources for Portable Programming'

It should show up via the index page in due course and is at

        https://svn.r-project.org/R-dev-web/trunk/Portability.html

now.  (R core members are welcome to add to it.)

Some of the articles linked there are very useful background on e.g.
32- vs 64-bit differences and how to write efficient shared libraries.

Some of these things are targets for R 2.2.0 (e.g. using lib64, controllng visibility), especially after gcc 4.0.0 is released (it was due this week).

Note to users of ix86 Linux: valgrind 2.4.0 is out and has solved almost all the instability problems of 2.2.0 on recent Linux kernels.
