But many of us svn sync e.g. R-2-12-branch rather than use snapshots.

I think the advice in the Windows binary download page

'This is a development version of R. It likely contains bugs, so be 
careful if you use it. Please don't report bugs in this version 
through the usual R bug reporting system, please report them on the 
r-devel mailing list---but only if they persist for a few days.'

is spot-on. It takes at least several hours, maybe a couple of days, 
for the package checks to reveal problems with changes in R-devel, 
especially platform-specific ones.
