[Mingw-cross-env-list] suggested GCC patch for exporting symbols needed by boost |

Hello,
GCC post version 5 seems to have a bug, that prevents some symbols from
exporting to the libstdc++, which prevents Boost from compiling. since then i
had downgraded to GCC 4.9.2 in MXE to fix this issue.
but after posting to a ticket reporting this same issue on the bug tracker for
GCC, they have admitted to fixing it and have since produced a patch, the patch
is not intrusive and only adds a Mingw conditional to export some symbols
whenever the "facet" codecvt_byname is called, which is used for code
conversion by Boost.
you can find all the info in this report:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66030
i have submitted a patch for merging to the Upstream, would appreciate if you
can look at it, test before/after Boost compile results, it is working for me
personally now, but it might be helpful to have confirmations from other users!!

proposed fix attached, merge request performed.
Thanks!
Hamza
