Hello,
Possibly somebody could give me a hint what the issue here is. In the
patch I attached, I enable multilib for x86 default mingw target
(i686-w64-mingw32). The core compilers are translating nicely. But
when it tries to build libgcc by -m64 it throws always the same error
message for any array : "error: size of array "..." is too large". I
am curious as the configuration patch is pretty equal to linux
version, but something I seem to miss here.
Thanks in advance,
Kai
