OS/Platform Support

[cx1111]

There appears to be various levels of support for several older/more obscure OSs/platforms, such as FreeBSD, and 16 bit MS Windows, MacOS < 10. It's also not clear which platforms and compilation methods we officially support. eg. See this comment about workarounds that are implemented and yet should be avoided.

While remaking this library, I'm not going to try to maintain the existing support. I simply do not have the ability nor the time to account for and test all these systems. This means that I'll be removing a lot of OS specific functions, variables, and macros.

Instead, we can take this approach as discussed:

• Aim to write platform independent code that conforms to the standard C++ distribution standards. eg. pay attention to:
  • Sizes of primitive data structures
• Support 64 bit Linux
• Add support for other major OS/Platforms one at a time. eg. Windows 32/64 bit, MacOS > 10, etc. Leverage CMake for multi-platform builds.

Also, we are going to remove dual C/C++ support. This will be a C++ codebase.
