Last SDK to fully support Windows 98?

I need to do a quick port to windows 98. My code is raw C/C++, I just need the headers, the compiler, and preferably some documentation to clarify what is supported b开发者_开发技巧y Windows 98 API.

What is the latest SDK (with a compiler) that still fully supports Win98, with the win98 documentation?

Suggestions:

1) Find yourself a compiler like OpenWatcom, DJGPP or Turbo C++

2) Whatever your current platform (including Linux), create a Win98 VM to test your code on
