Is this your first attempt to debug a gdal executable?  It should work
similarly to the others.

I suspect you are building with libtool and the gdal/apps/dumpoverviews
is just a script running the binary in the gdal/apps/.libs directory.  You
can try running gdal/apps/.libs/dumpoverviews in ddd, but that can be tricky
because library stuff might not be setup properly.

I suggest configuring --without-libtool and doing a clean build.  Libtool
is just a big pain in the butt while developing (IMHO).
