I had a peek inside /usr/include/dirent.h on CentOS 5.2 and DT_DIR only gets
defined if "__BSD" is defined.  Apparently adding "-std=c99" turns that off.

We probably want to blindly add "-D_GNU_SOURCE" when compiling under GCC.

It should be harmless on non-glibc systems.

    Defining _GNU_SOURCE on non glibc platforms shouldn't hurt,
    so I simply dropped the switch.
