Summary 0011748: Warnings when building Windows Tiles
Description Not a bug at all, but there is no other appropriate category to submit this under. An "issue" category would be nice for issues like this one.

Building the most recent version of Windows Tiles, using MSYS2 MINGW64 on a Windows machine, gives the warning messages below, when windowmanager-sdl.cc compiles.

<built-in>: warning: redundant redeclaration of 'unsigned int __builtin_ia32_crc32qi(unsigned int, unsigned char)' in same scope [-Wredundant-decls]

Yeah, I've been seeing these building in a VM for a while. As far as I can tell they're harmless and something internal to MSYS2, but I haven't really tried to track it down.
