     Interesting removal of <dirent.h>; reducing the scope of places
     that get this include? (good idea)

Thumbs up.

I believe the __USE_LEGACY_PROTOTYPES__ uses around <dirent.h>
were added by Jerry Thornbrugh when our official build platform
was Solaris 10u6 or something like that.

P.S.
Alan, I'll setup a repo for pushing this changeset when you
get through the review process.
