It builds fine here. How do you build it?

[tomay3000]

@lazka I am using a different variant of mingw-w64, the one with sjlj exception model and gcc v8.1.0

I am rebuilding another version of mingw-w64 to use sjlj exception model and gcc v8.3.0 this time and try see what I get.

I needed sjlj not dw2 for my needs, to link against MSVC built DLLs.

Dwarf Crashed a lot for this kinda DLLs.

OK, the error indicates that MS_WINDOWS isn't defined, which means that your toolchain doesn't define __MINGW32__ or _WIN32 for some reason: https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-python2/0110-MINGW-translate-gcc-internal-defines-to-python-platf.patch

I turns out that it compiles without issues in the default configuration: "the prebuilt dwarf2 gcc and crt". May be I was missing something in my custom "sjlj" configuration. I guess I am falling back to the EASY and ALREADY prebuilt default configuration.
