Compilation under Windows now works fine, many thanks.

I had however a problem under windows. Your scheme with the rootsys.h file does
not work under windows, since the ROOTSYS variable usually points to something
like c:\root. If I follow your scheme, I get following in rootsys.h

const char* rootsys = "c:\root";

where the "\r" is interpreted as a carriage return. I did not find a clever way to
convert this to 

const char* rootsys = "c:\\root";

in the Makefile, so for windows I just make it empty, like

const char* rootsys = "";

I changed your src/main.cxx to check for an empty rootsys, and if yes just take
the environment variable. I committed that change, I hope it's ok.

There is one small warning left whern running under windows;

C:\roody>bin\roody
Error in <TWinNTSystem::BaseName>: name = 0

Do I have to worry about that?
