Bug ID: 52787
           Summary: Invalid function prototype for "RegisterUserApiHook"
                    when compiling for C++
           Product: Wine
           Version: 7.5
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

      Distribution: ---

This change added a function prototype which does not compile in C++:
https://source.winehq.org/git/wine.git/blobdiff/e02a7e579cc48079d70f2ef00957...

This is invalid C++ syntax as "new" is a reserved keyword:

WINUSERAPI BOOL WINAPI RegisterUserApiHook(const struct user_api_hook *new,
struct user_api_hook *old);

This is what the compiler generates:

"error: invalid parameter name: 'new' is a keyword"

This means any C++ code trying to include "windows.h" will fail with that
error.

The fix is fairly simple. That line should be changed to this to fix it:

WINUSERAPI BOOL WINAPI RegisterUserApiHook(const struct user_api_hook
*new_hook, struct user_api_hook *old_hook);

(i.e., rename the variable).
