A 64-bit build on Windows, whether a Cygwin build or a MinGW64 build, doesn't need the force_align_arg_pointer, since the 64-bit ABI requires the 8-byte alignment. The __x86_64__ is there to exclude the 64-bit Cygwin build. If it can also exclude the MinGW64 build, we don't need any MinGW64-specific symbols there. > Eli, both MinGW and MinGW-w64 compilers support sjlj and Dwarf exception > methods on x86. But what is the default one? That's what's important. > And since when we do care about C++ here? ;-) At least the DWARF2-based exceptions machinery comes into play in C programs as well, see the few Emacs crashes we had with libraries linked against the libgcc DLL.
