Because cross-compiling binaries for Windows is easier than building natively

I want Microsoft to do better, want Windows to be a decent development platform-and yet, I constantly see Microsoft playing the open source game: advertising how open-source and developer friendly they are - only to crush developers under the heel of the corporate behemoth's boot.

The people who work at Microsoft are amazing, kind, talented individuals. This is aimed at the company's leadership, who I feel has on many occassions crushed myself and other developers under. It's a plea for help.

The source of truth for the 'open source' C#, C++, Rust, and other Windows SDKs is proprietary

You probably haven't heard of it before, but if you've ever used win32 API bindings in C#, C++, Rust, or other languages, odds are they were generated from a repository called microsoft/win32metadata.

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

1. Combined type and variable/field declaration, inside a struct scope [https://godbolt.org/g/Rh94Go]

struct foo {
   struct bar {
 int x;

Linker error messages related to libc and libstdc++

We run into the dreaded

/usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.18' not found

error messages a lot around here. This article is an attempt to explain what's going on with that.
