Regarding my previous message, I have combined the various C  
functions I call from R into one shared object, and now R CMD build  
works fine on Windows. It still might be worth looking into why  
R_HOME/etc/Makeconf macros are available in Makevars.in under unix  
but not in Makevars.win under Windows...
