-Subject: [PATCH] crt: Handle .ctors and .dtors within mingw-w64
-
-When building with clang we currently assume you will be
-linking with llvm's lld or a bleeding edge binutils.
-In future this will become the default method once
-binutils support has settled and bumped a few versions.
----
-This patch is up for review at
-https://sourceforge.net/p/mingw-w64/mailman/message/36002789/.
