Creator fails to set up the build environment with MSVC 2008 and
Windows Mobile SDK 6.  This is caused by two problems:

1. The toolchain was being searched for in
   C:\Program Files\Microsoft Visual Studio 9.0\VC\VC
   The correct path is
   C:\Program Files\Microsoft Visual Studio 9.0\VC

2. Include statements in mkspecs were not being processed.  All of the
   important variables are set in files included from the
   wincewm60{standard,professional}-msvc2008 mkspecs.
