See if stdio allows you to specify delete sharing when
opening the file.
I don't know what delete sharing is exactly, but the File
constructor simply calls fopen and I don't see any option for
the Windows fopen that seems to do it:

The fopen variant that allows you to specify sharing is:
http://msdn.microsoft.com/en-us/library/8f30b0db.aspx
But it does not mention delete sharing there.
CreateFile allows sharing to be specified for delete however:
http://msdn.microsoft.com/en-gb/library/windows/desktop/aa363858(v=vs.85).aspx
So... you could:
- Call CreateFile giving you a "handle"
- Call _open_osfhandle to get a "file descriptor"
- Call _fdopen on the file descriptor to get a FILE* for it
But! I agree with Adam, leave it as a thin wrapper. Being a
windows programmer by trade I would expect the remove to fail,
I would not expect all my files to be opened with delete
sharing enabled by default.
Thanks for all the info. I'm looking at it from the point of
view of a beginner or someone who just writes a quick D script
that does something like this. They may find it confusing that
it works on linux but doesn't work on Windows, especially given
the confusing error message.
But it is good practice to close a file before deleting and if D
prefers to have thin wrappers around OS APIs, that implies less
hand-holding like this, so maybe we just tell such people to
close the file first.
