Over time, Microsoft has essentially dropped support for the POSIX mode and
instead recommends porting POSIX applications to Win32. See:

calls in Win32 mode programs. If you want to use a POSIX call that is not

the Borland compiler, but it wouldn't be easy. If you want to use the
Cygwin.dll library, it is easiest to use it with the free Cygwin GCC
