Hi, thanks for the patch. I don't think we can apply it now, as the
GCC trunk is only open for regression fixes until GCC 8 is released.
How was this tested? Will it work for all versions of mingw that we
support? Is TLS enabled for native builds? (If so we definitely need
this, because otherwise mingw cross-compilers are not ABI compatibnle
with native ones).
