# The penalised fit runs the folds of a cross-validation on threads where the caller asks for it,
# through `std::thread`. On a toolchain whose standard library reaches pthreads that has to be
# said at compile and at link, or the threads throw at run time on the machine that built them
# fine. `SHLIB_PTHREAD_FLAGS` is what R sets to whatever the platform needs, and is empty where
# nothing is needed.
