Bug ID: 46939
           Summary: propvarutil.h: missing extern "C"
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs@winehq.org
          Reporter: sadko4u@gmail.com
      Distribution: ---
This header is a part of MinGW-W64 compiler.
When trying to #include <propvarutil.h> and use the 'PropVariantToInt64'
function, we get a linker error.
Looking for the latest master branch:
https://github.com/wine-mirror/wine/blob/master/include/propvarutil.h
Seems that there is no extern "C" around function prototypes.
Such workaround fixes the problem:
#include <shtypes.h>
#include <shlwapi.h>
#if defined(__cplusplus)
extern "C" {
#endif
#include <propvarutil.h>
#if defined(__cplusplus)
}
#endif
Fixes the problem
