With 64bit multilib toolchain is the same situation as with 32bit
multilib toolchain

I.e. SJLJ can't be used for 4.8(and later)-x86_64?

Well, __SEH__

Because I a few months can not build trunk with sjlj successfully.
I wrote about this in the gcc-help mailing list, I think twice.

My configure line is:

Hi,
the cause for this is that SEH exceptions are only present for x64
64-bit target. There is no such support for 32-bit (mainly caused by
patent issues). Therefore if you want to build multilib for mingw,
then please switch back to SjLj-exception mechanism.

Hi!
When I try to build gcc from trunk with mingw-w64 I successfully build
only 64bit with seh exceptions. Other builds stop on error
../../../../../../mingw-sources/gcc-trunk/libgcc/unwind-c.c:238:1:
warning: no previous prototype for '__gcc_personality_seh0'
