Under Windows "sysopen" requests that direct API calls (CreateFile et
al.) are used instead of the libc wrappers.  This may or may not
improve the performance.

Using "sequential" is a hint to Windows to assume that a file is in
general access in a sequential manner.  This will have an affect only
with a future libgpg-error.
