Summary:                    CMake possibly fails to launch devenv.com when
disable8dot3 is set on NTFS
Description: 
CMake applies GetShortPathName() on the compiler path with the purpose to
generate a space-free string - this doesn't work if the path to devenv.com a)
contains a directory with spaces (which it usually does, due to the "Microsoft
Visual Studio X" directory) and b) said directory was created (e.g. MSVC was
installed) when disable8dot3 was set to 1.

The resulting error is rather cryptic - "Check for working C compiler" fails
with the error message "%1 is not a valid Win32 application" (including the
verbatim %1), as a result of CreateProcess() trying to launch the file
"C:\Progra~2\Microsoft".



Additional Information: 
As a workaround the user can give the MSVC directory a short-name, after which
cmake works fine:

> fsutil.exe behavior set disable8dot3 0
> fsutil.exe file setshortname "Microsoft Visual Studio 9.0" msvc~90
> fsutil.exe behavior set disable8dot3 1
