Looks like it's some kind of problem with underscore prefixing.

`D2rt5tlsgc14processGCMarksFNbPvMDFNbPvZiZv' should likely have an
underscore appended.

Our MinGW port is probably mostly broken, but we need a good way to
run the testsuite for MinGW to really have a useful MinGW port. Once
I've got some time for this I want to take the standard DMD test
runner, make it a real stand-alone program and add support for cross
compiler testing using ssh/scp. Once we have that it should be possible
to reliably test the MinGW port.

BTW: As MinGW mostly uses the standard MS runtime and upstream
druntime/phobos now supports these we'll probably only have to update
version blocks. TLS could be a problem, but we could just compile with
emutls for now which should work.
