title: Issues using perforce command line under cygwin
body: <p>So, virtually cannot use the the perforce command line for anything other than syncing.
  My workspace root is mapped to C:\
  Here's a line of my client spec:
  //claims1.0/main/... //cthiel/code/claims1.0/main/...  </p>
  
  <p>Any time I fire up cygwin and attempt to work with any files in my depot (such as p4 edit ), I get an error along the lines of:
  Path '/cygdrive/c/code/commonTest/main.p4ignore' is not under client's root 'C:\'.  </p>
  
  <p>The paths aren't matching up, because the equivalent of C:\ for cygwyn is /cygdrive/c. So it's never able to find files with the perforce command line.  </p>
  
  <p>Is there a way to fix this? It's highly annoying.</p>
