SLOCCount plugin fails with Windows/Cygwin SLOCCount execution

      In our setup we have a master Hudson machine running on Linux with one slave
      macine running Windows XP. This last machine is responsible for any
      Windows-specific builds in our environment. To have some metrics, we make use of
      SLOCCount both for the Linux and Windows projects, the SLOCCount plugin works
      perfect for our Linux projects but fails to work on the Windows ones.

      On Windows SLOCCount itself has to be executed from CygWin (Linux Emulation)
      which works without problems and gives the proper output format. An extract of
      this file is as follows:

      Have a non-directory at the top, so creating directory top_dir
      Adding /cygdrive/h/###_Hudson/workspace/IvAp_v1.x/ivap/src/BetaUpdate.exe to

      Adding /cygdrive/h/###_Hudson/workspace/IvAp_v1.x/ivap/src/IvAp.sln to top_dir

      Creating filelist for IvapMsgLib

      to top_dir

      As soon as Hudson starts collecting the results, we find this exception in our
      console log:

      Based on a quick look at your source code I am assuming this is a problem
      related to the file separator. I.e. the data is collected on a Windows slave
      (separator = ), while the paths in the file are from CygWin (separator = /). I
      suggest to use both for detecting the paths.
