You should make configure.bat do the equivalent of:

if sequence( dir(".svn") ) then 
    puts( fd, "SVNDIR=.svn\n" ) 
else 
    puts( fd, "SVNDIR=svn~1\n" ) 
end if     

And then put $(SVNDIR) as the dependency for rev.e. That will ensure the binaries will report the correct svn number at start up no matter which file system you are using.
