Building via MSYS2 on Windows is broken in v.1.5.1

[define-private-public]

The culprit looks to me like it's those intrinsic calls in fastapprox (or maybe I'm wrong). I followed the guide on the wiki how to build with MSYS2, updated all of my packages. The GCC version is 9.3.0 Here is the build output:

Haven't looked into the actual cause of those "errors", but they don't actually prevent you from building libmypaint.

Log for the successful build of 1.5.1 on MSYS2 yesterday: https://ci.appveyor.com/project/jonnor/libmypaint/builds/30996672/job/b7axhjk6eah9fw6a

As you may note, the lines you pasted are present in that log as well, but are actually of no consequence for the output.

It's actually not a msys2-specific problem. Also happen in Debian too: https://buildd.debian.org/status/fetch.php?pkg=libmypaint&arch=amd64&ver=1.5.1-1~exp1&stamp=1582496604&raw=0

[define-private-public]

Debian? I run Ubuntu normally (which IIRC is Debian based). I've been able to build it just fine here. I've also got an OS X machine handy. Would you like me to do a build there too?
