The conversion from unix-style /cygdrive/c/paths to /c/paths when
handing the paths to native tools does a simple search and replace. Any
cygwin paths which don't conform to /cygdrive/X are all horribly mangled
by the to and from process, so /home and /tmp don't work :-(

I burned some time trying to make it work, but higher priority stuff
scuppered me. Here's a diff of some hacking I was playing with to try
and work through it.
