I know only a little rust, and nothing about bindgen, but I think you want to read this and apply some whitelisting so you are not trying to bind the entire C++ std library.

I tried making several types opaque, but ran into #11.
https://github.com/ctaggart/octh/blob/opaque/build.rs

I think this is coming from random.h or opt_random.h. Those are the only files that have _UIntType.
C:\Octave\Octave-4.2.1\lib\gcc\x86_64-w64-mingw32\4.9.4\include\c++\bits\random.h
Should try disabling it and seeing what happens:

#define _RANDOM_H 1

[ctaggart]

fixed by #22

[ctaggart]

This is an issue again because of #28.
