Ouch - this is broken.  You should _never_ need to #include a system
header inside C++ guards.

<dirent.h> should be providing the C++ guards.  If it is, this instance
in <sys/dir.h> is redundant; if it isn't, then <dirent.h> needs fixing.

/me goes to check...
Hmm - <dirent.h> _is_ providing C++ guards, but then it includes
<sys/dirent.h> inside guards.  Which means <sys/dirent.h> needs fixing too.
