Author: pal1000 <[email protected]> Date: Fri Mar 1 12:30:15 2019 +0200 scons: Fix MSYS2 Mingw-w64 build. Reviewed-by: Jose Fonseca <[email protected]> This patch is based on https://github.com/msys2/MINGW-packages/blob/28e3f85e09b6947ea80036c49f6c38f1394f93ca/mingw-w64-mesa/link-ole32.patch but with tweaks to avoid MSVC build break when applied. v2: Create Mingw platform alias pointing to windows host platform define to avoid spurious crosscompilation; v3: Fix obviously wrong compiler flags for swr driver; v4: Update original patch URL because it has been relocated; v5: Don't bother patching autools stuff as it's not used by MSYS2 Mingw-w64 build and it's days are numbered anyway; v6: After Mingw posix flag fix in 295851eb things are far simpler as we don't need more linking of uuid, ole32, version and shell32 than what is already in place.
