[R] Cross-compilation of R and ld bug ?

[Prof Brian Ripley]

There are two problems here:

1) your binutils is not current.
2) your R is not current.

Updating either will solve this, but please update both.
Almost up-to-date cross-compilers are (as ever) available from

http://www.stats.ox.ac.uk/pub/Rtools/

(If you want to compile R-devel you will need to update the mingw, which 
can be done from the i386 distribution.  I will rebuild the 
cross-compilers in due course.)
