I have a similar question: I had to modify 'profile' to change
   $PATH=xxxx:$PATH
to
   $PATH=xxxx

How can I simply add $SYSTEMROOT:$SYSTEMROOT/system32 to this? It 
doesn't work as-is because $SYSTEMROOT = C:\Windows (and this is 
therefore not interpreted by the path). Rephrasing, what do I use to 
translate "C:\WINDOWS" to "/cygdrive/c/windows"?

I had to do this because some nasty things in my path were causing 
problems (e.g. ClearQuest/ClearCase)

TIA,
Jason.
