Most of them are complaints about too many ifdefs and complaints about C++ code in .h files.

The interesting ones are:

zeo++/psd.cc:822:15: error: Uninitialized variable: volFraction [uninitvar]

          if (volFraction >= TOL) {

is a false alarm

but

zeo++/holograms.cc:946:9: error: Uninitialized variable: int_edge_radii_bins [uninitvar]
        int_edge_radii_bins[bin_index] += 100;  // 100 so we can get percentages
        ^

looks real

The two issues mentioned above are fixed.

We don't care about the resource leak in the voro++ example.
