I would be surprised if GCC + SEH is as reliable as DWARF. http://gcc.gnu.org/wiki/WindowsGCCImprovements says GCC doesn't do Windows SEH at all, but the real reason SEH isn't in mainline GCC is due to patent fears, there has been an implementation for some time. I assume the mingw-w64 developers decided to merge that patch anyway.
The MinGW-w64 page states that SEH is only patented for x86, not on x64, which is why the 32 bit version only has Dwarf or SJLJ as options. The 64 bit version is SEH or SJLJ.
If you intend to ever post about SEH to the cfe-dev@ (Clang) list, don't bother. All discussion on the subject or even of laying groundwork for SEH or implementing something similiar under a generic name will be immediately shut down and gagged.
