+# If we need to download a custom MinGW, do so here and set the path
+# appropriately.
+#
+# Here we also do a pretty heinous thing which is to mangle the MinGW
+# installation we just downloaded. Currently, as of this writing, we're using
+# MinGW-w64 builds of gcc, and that's currently at 6.3.0. We use 6.3.0 as it
+# appears to be the first version which contains a fix for #40546, builds
+# randomly failing during LLVM due to ar.exe/ranlib.exe failures.
+#
+# Unfortunately, though, 6.3.0 *also* is the first version of MinGW-w64 builds
+# to contain a regression in gdb (#40184). As a result if we were to use the
+# gdb provided (7.11.1) then we would fail all debuginfo tests.
+#
+# In order to fix spurious failures (pretty high priority) we use 6.3.0. To
+# avoid disabling gdb tests we download an *old* version of gdb, specifically
+# that found inside the 6.2.0 distribution. We then overwrite the 6.3.0 gdb
+# with the 6.2.0 gdb to get tests passing.
+#
+# Note that we don't literally overwrite the gdb.exe binary because it appears
+# to just use gdborig.exe, so that's the binary we deal with instead.
+#
+# Otherwise install MinGW through `pacman`
