This serie ensures a couple of Wine include files are properly defined when included from C++ code. It mainly adds a extern "C" { ... } around the various definitions. The list of modified files has been determined by: - checking Wine headers without extern "C" instruction, while SDK one has it, - not all files matching that criteria have been patched (eg DDK files have been left out) - some files have been patched even if their current content doesn't require it (ie no variable nor extern function definition), esp. when their SDK equivalent has a lot of such definitions (so that the c++ guard is not forgotten when the header file is updated), - search criteria is also not 100% accurate (eg missing EXTERN_C macro). Been triggered by bcrypt.h failing to be used in C++ code (didn't test for the others). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10303
