As long as "ln -s a.exe b" produces b ==> a.exe (and not b.exe), exim is OK.

I think we are OK. The 4.60 version of exim released today has a postinstall
script that deletes any offending exim.exe symlink. Also exim-config now 
detects if an exim.exe symlink or file masks the exim symlink and it acts
appropriately.
