Building R under gcc 3.4.5 on Windows will no longer be supported as from 
R 2.7.0.  The default settings in the trunk (R-devel) are for the new 
version of Rtools,


in which gcc is 4.2.1.  This also contains gcc-sjlj.exe, so can be used to 
build R 2.6.x as well.  It will become the default Rtools.exe in due
