Thank you for teaching me the fact that this style of comment isn't in C89.

This may be completely irrelevant, but sometimes adding DECLSPEC_HOTPATCH to a function resolves strange crashes. Ideally we would include DECLSPEC_HOTPATCH in the definition of WINAPI, but GCC doesn't like it being slipped onto function pointers, so we've just been adding it on an as-needed basis.

I have noticed that wintypes.dll is used in a lot of Microsoft software, including dot net framework.

Minecraft Windows 10 laucher (The on that can launch bedrock) also require a working wintypes.dll

[Daniel Tang (＠danielzgtg)]

@Fox2Code Can you be specific about which Minecraft launcher?

The official (NOT bedrock?) on at https://launcher.mojang.com/download/MinecraftInstaller.exe gives me the following:

```
0164:fixme:ntdll:NtQuerySystemInformation info_class SYSTEM_PERFORMANCE_INFORMATION

Unhandled Exception:
System.IO.FileNotFoundException: Could not load file or assembly 'Windows.Foundation.UniversalApiContract, Version=7.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

```

The one at https://launcher.mojang.com/download/MinecraftInstaller.msi doesn't crash and appears fine:

![image](/uploads/b980647b0bc6c1feb8bd2a81122e7031/image.png)

I Googled the unofficial one, and it gave me the following:

```
0138:fixme:netprofm:connection_point_Advise 0412AB90, 04022C18, 05C6FB04 - semi-stub
Application could not be started, or no application associated with the specified file.
ShellExecuteEx failed: Bad EXE format for Z:\home\home\Downloads\net6.0-windows10.0.17763.0\BedrockLauncher.exe.
```
> also require a working wintypes.dll

Neither crash mentions `wintypes.dll`, so they appear to be therefore off-topic for this MR. Please file a new bug at https://bugs.winehq.org/buglist.cgi?quicksearch=minecraft
> including dot net framework

I use https://wiki.winehq.org/Mono instead of Microsoft's .Net framework. If .Net isn't working please look at the bug tracker
