[KOS] semaphore.h?

[Luke B. <ka...@gm...>]

Hi,

I've tentatively started porting SDL 2 to KOS - I have it successfully
compiling, I've just started swapping out all the generic/dummy
implementations of the subsystems with KOS specific ones. I've done the
timer backend and now I'm working on the thread backend.

I noticed that the existing pthreads backend in SDL 2 would probably work
on KOS, but SDL looks for "semaphore.h" which apparently doesn't exist in
KOS, but does exist in newlib. There also seems to be a very similar
semaphore implementation in "kos/sem.h".

Before I implement a wrapper around kos/sem.h to make the SDL 2 pthreads
stuff compile, I just wondered if there was a reason why semaphore.h isn't
available in KOS by default, and would it be better if I perhaps altered
the semaphore.h from newlib (in a similar way to pthread.h) and sent a
patch to KOS?

Thanks,

Luke.
