On windows, many executables have an assembly manifest embedded. This
sets among other things the JDK version. Our current handling of this is
sub-optimal, using template files that are modified at build time.
Instead, a command line option to MT, the manifest processor, can be used.
At places we also try to include manifest information twice, using the
old style of declaring the manifest file in an .rc file. This is not
needed when we use MT for post-processing.
