Not sure about the Makefile, but see

https://stat.ethz.ch/pipermail/r-devel/2011-March/060260.html

also on my own machine

Z:\> R CMD INSTALL Biobase
* installing to library 'C:\Users\User\Documents/R/win-library/2.13'
* installing *source* package 'Biobase' ...
...

** testing if installed package can be loaded
Error: '\U' used without hex digits in character string starting "C:\U"
Execution halted
ERROR: loading failed
* removing 'C:\Users\User\Documents/R/win-library/2.13/Biobase'
* restoring previous 'C:\Users\User\Documents/R/win-library/2.13/Rsamtools'

whereas under 2.12

Z:\>R CMD INSTALL Biobase
* installing to library 'C:\Users\User\Documents/R/win-library/2.12'
* installing *source* package 'Biobase' ...

and everything is fine.

Z:\> R --version
