rand_r missing stdlib.h on Windows about lightfm

[maciejkula]

This is due to the fact that rand_r is part of glibc which you are obviously not using.

It may work for you as-is if you use gcc for compilation. Alternatively, I have opened #42 which includes its own rand_r implementation. I obviously cannot use MSVC's impl as that would only compile on Windows!

Having said that, you may run into more problems still with openmp support and so on; I cannot support Windows myself but would be happy to accept changes that make it work on Windows.

It would be great if you could check out #42 and see if it solves your problem.

@maciejkula #42 compiles on my machine. Will keep you posted if I incur into openmp issues

[maciejkula]

Thanks, please let me know if you succeed in using it.

[maciejkula]

Does it work fine?

[gglanzani]

Hi Maciej, I'm expecting to have some time on Wednesday afternoon. I promise to let you know by then (like, really promise!)

[gglanzani]

@maciejkula Contrary to my promise, I tried it a little earlier (now). It works (i.e. in the example notebook I arrived up until the AUC score, so I guess that's enough to test the openmp).

Fantastic, I'll merge my changes and cut a new release.
