More likely you are cross-compiling R to run under Windows.

Who said you should `make R'?  That is not in the instructions in 
src/gnuwin32/INSTALL.  If you do that you should get

gannet% make R
make: *** No rule to make target `R'.  Stop.

So R_EXE is not defined.  Setting it is part of the instructions.

User error!  If you follow the instructions it does work, at least in an 
English-speaking locale.
