Problem with #includes in mex file (seems to find the files, but creates a lot of errors - see below)

When I have a mex-file that works fine (with standard mex-includes) and then I simply put a new #include on top (without otherwise changing the code), I get 100s of error-messages like the ones below. It doesn't seem to matter, which includes. For example, I needed a better random number generator, so I tried "#include <random>". The error messages below are just the first few...

Seems like you need to play with the mex include path:
