Hi,

On Windows CE, the toolhelp functionality  is implemented on
its own dll.  Additionally, (and because of the former), the snapshots
must be closed with a special close
function - CloseToolhelp32Snapshot - unlike the "desktop" Windows
versions, which use the standard CloseHandle.  The current code isn't
doing it right.  This patch fixes it.

(in case the toolhelp_get_dll_name hunk isn't clear in
the diff, I'm just 'reorganizing a bit'/'removing the goto'
to minimize the #ifdefery.)

OK?

Cheers,
Pedro Alves
