Hello Pali,

Compiling GCC for aarch64-w64-mingw32 target.
mingw-w64-crt/crt/crtexe.c:171:2: error: #error unsupported platform

__SEH__ is not defined yet. That work is still in progress for GCC.
It would be great to find a temporary workaround that will allow to build
MinGW from upstream. Once the patch series with SEH implementation is merged,
the workaround will be removed.

Thank you.
