What is the procedure for requesting updates to the MinGW w32api package (header files and import libraries)? I bumped into a few APIs introduced by Windows 10 which are not covered by the import libraries (so the only way to use them is to link against the DLL itself). Is it enough to mention their names in the ticket, or should I submit some additional information, like an actual patch to the relevant .def file(s)? (It is not clear to me whether the *.def files are maintained by hand or are produced by some tool.) And what about the header files and the prototypes there, and also definitions of struct's and constants that those newer APIs require? Is it acceptable to use in our headers the definitions from MSDN? Thanks.
