From 37d98abdc77cfbd158b453d22629e5c7d020c878 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 15 Sep 2020 12:18:03 +0200 Subject: [PATCH] qga/commands-win32: Fix problem with redundant protype declaration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When compiling QEMU with MSYS2 on Windows, there is currently the following error: ../qga/commands-win32.c:62:24: error: redundant redeclaration of 'CM_Get_DevNode_PropertyW' [-Werror=redundant-decls] 62 | CMAPI CONFIGRET WINAPI CM_Get_DevNode_PropertyW( | ^~~~~~~~~~~~~~~~~~~~~~~~ In file included from ../qga/commands-win32.c:26: C:/tools/msys64/mingw64/x86_64-w64-mingw32/include/cfgmgr32.h:840:26: note: previous declaration of 'CM_Get_DevNode_PropertyW' was here 840 | CMAPI CONFIGRET WINAPI CM_Get_DevNode_PropertyW(DEVINST dnDevInst, const DEVPROPKEY *PropertyKey, DEVPROPTYPE *PropertyType, PBYTE PropertyBuffer, PULONG PropertyBufferSize, ULONG ulFlags); Seems like this protype is sometimes available in the cfgmgr32.h header, and sometimes not. Let's silence the compiler warning here to let the build pass with -Werror, too.
