Subject: [PATCH] guiddef.h: Use __declspec(selectany) on GUID declarations.
|
|
|
|
If __declspec(selectany) is not used on the prototype but later used
|
|
on a definition, GCC 6+ seems to ignore it, and you can get
|
|
multiple-definition errors at link time.
|
|
|
|
That situation can arise in code like Microsoft's usbview utility that
|
|
has multiple translation units including the following headers in this
|
|
order: windows.h, initguid.h, winioctl.h.
|
|
|
|
However, this patch cannot be upstreamed to mingw-w64 because it
|
|
breaks older versions of GCC, and MSDN says that putting selectany on
|
|
a declaration is "incorrect". Once GCC is fixed, we can remove this
|
|
patch.
