[Rd] Updates for building R-devel for Windows

[Prof Brian Ripley]

If you are building R (especially R-devel) for Windows, you will need to 
update your tools.

First, we now require binutils-2.16.91-20050827 (and even 2.2.1 
effectively did).  There is a patched ld.exe for that available from the 
Rtools site, which should be used if you intend to distribute compiled 
packages.  (It overcomes a bug only seen on NT4: the patched version is 
being used for the pre-compiled packages Uwe Ligges makes.)

Second, the recommended gcc 3.4.4 compilers have been replaced by 3.4.5 
ones.  As the 3.4.4 builds are not longer available, we recommend you do 
use the currently available 3.4.5.

Third, I have updated my cross-compiler suite to binutils-2.16.91-20050827 
(with the patched ld.exe), mingw-runtime-3.9 and w32api-3.5, and the 
updated suite is required to build R-devel or R-patched.  After a 
considerable struggle I have managed to cross-build all of gcc-3.4.5, so 
full C++ support is available again.
