[R] cross compiling R for Windows under Linux

[Lars Schouw]

After trying all day here in Tokyo.
I foudn a word around for the problem copying the
header files from 
mingw/i586-mingw32/include 
to 
mingw/include

so at least I can compile that part...

Strugelling with tcl right now..
But it looks better now ;)
