Yes, you can check in .First.lib, or in configure.win, or whereever, 
*BUT* that does not help, e.g., for the CRAN repository.
If I am compiling under 2.1.0 release, the package will fail my checks.
If I would be compiling under R-patched, it will not fail the checks, 
but don't work for several users who probably do not want to use 
un-released versions of R.

I think the best way is to wait for the next release of R.

Is there a schedule for R-2.1.1, BTW?
