The problem is not the headers, you can include them per system using an ifdef.
The problem is that linux doesn't have the same functions as far as I can tell.
The current linux standard is pthreads. There is also fork/vfork (create a
child process) and there used to be light weight threads years ago, can't for
the life of me remember the exact name and reference. I think it came from sysv
but not sure. Maybe someone else has a better memory than me.
In hpc (high performance computing), OpenMP and MPI are more prevalent as
they are designed for mathematical parallel processing and takes care of a
lot of the overhead specific to these aims, but they are probably what you are
looking for at the moment.
