  MSVC: Use <io.h> as an alternative for <unistd.h> Only the input/output functions from <unistd.h> options are used, so using <io.h> when building with MSVC should be enough. The inclusion of the header in context-priv.c does not seem to be needed (tested on GNU/Linux) and so it is removed. Signed-off-by: Ran Benita <ran@unusedvar.com>
