One of the projects listed on this page
(http://www.prowiki.org/wiki4d/wiki.cgi?GrammarParsers)
may be useful to you.

Many of these projects are probably inactive, but Enki
(http://www.dsource.org/projects/ddl/wiki/Enki)
is one of the most recent options.

As BCS mentioned, his Dparser
(http://www.dsource.org/projects/scrapple/browser/trunk/dparser/dparse.d)
is a recent effort in parsing.

I've been interested in "The Language Machine"
(http://languagemachine.sourceforge.net/),
but I've never tried it myself and it might need some work to get it to 
compile with the latest version of D.

I'm not sure which project you're referring to but they probably used a 
combination of automation and hand-editing to convert the C++ source 
into D (the front end of DMD has been open-sourced).

Perhaps you're thinking of an effort that's in the Bindings project
(http://www.dsource.org/projects/bindings)?
