That would provide a lot more flexibility, including:

* the ability to implement O_INHERIT (i.e. O_CLOEXEC) correctly

* the ability to reimplement open and friends using the underlying NTDLL 
functions (Unicode-friendly, >260 characters per path, etc.)

* the ability to use _free_osfhnd in the close module

However, it is bad that these data structures can change for every 
version of MSVC.  At some point, you have to balance flexibility and 
maintainability.
