Lpc2000

I found the solution to my own problem. Eclipse didn't find the
cdt-"feature", because it was not the right version. The version of
the plugin was org.eclipse.cdt_3.1.0, while all the other plugins were
3.1.1. 

So I changed the name of the map for this plugin to 3.1.1, and now,
everything seems to work fine. 

This may or may not be the most catholic approach, but it worked and I
thought I'd share it for posteriority.
