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

[Stéphane Dray]

Not sure to really understand 1) . The makefile (available at 
http://cran.r-project.org/doc/contrib/Makefile-rcb) use  wget 
--passive-ftp 
http://www.stats.ox.ac.uk/pub/Rtools/mingw-cross5.tar.bz2;  This version 
seems to be the current, I am correct ? Note that :

stephane at pcdray:~/Rdev/CrossCompileBuild$ cross-tools/bin/i586-mingw32-ld -v
GNU ld version 2.16.91 20050827
stephane at pcdray:~/Rdev/CrossCompileBuild$ cross-tools/i586-mingw32/bin/ld -v
GNU ld version 2.16.91 20050827


However, I have use R-2.4.1 and everything seems ok.

Thanks.
