Unfortunately, I have to agree with Nicolas.

This is the reason why the MingW and Wine projects reimplemented all the
headers based on the MSDN documentation. Because using non-free headers
is very debatable and usually considered as not ok by US lawyers (and
nVidia is a US company)

Yes, but not for the header.
