Hallo!
borland C++ compiler (5.5). And I know there is also the gcc for windows(?). But the procedure seems to be much more complicated than on linux.
There is mingw and cygwin. But if you compile it with cygwin you will always need cygwin.dll, so I do it with mingw.
You shouldn't have to change much in the linux makefile to compile with mingw.
