[Qemu-devel] [PATCH v4 1/2] qga: add additional win32 cflags and libraries

[Kirk Allan]

Test if –-extra-cflags is being used to include flags such as
_WIN32_WINVER and WINVER to gain additional functionality offered
by Windows Vista/2008 and newer.  If not, default WINVER to 0x501.

Add the iphlpapi library to use APIs such as GetAdaptersInfo and
GetAdaptersAddresses.
