It's not just SEH support that's missing in mingw (in fact, GCC mingw 
already supports SEH on x86_64 and llvm-mingw on all targets), but it'd 
also need some sort of __try/__except support (or something similar), 
which is not present in GCC.


clang already supports it on all targets. I gave it a try when I was 
working on clang support and it looked promising. Back then, I decided 
to put it aside until clang builds are generally in a better shape. I 
just gave it another quick look and with the attached patch, I was able 
to build x64_64 Wine. Unfortunately it fails to run iexplore (my quick 
test), so there is more work needed. If you'd like to give it a try, use 
something like this for configure:

configure CROSSCC=clang CROSSCFLAGS="-g -O2 -DUSE_COMPILER_EXCEPTIONS" 
--enable-win64
