WIN32, _WIN32 and option: pragma

Hi Everyone,

Would someone mind clarifying how I should be using the windows
platform macros. My understanding is:

- WIN32 is defined by the VM build scripts on Windows 32 bit only
- WIN64 is defined by the VM build scripts on Windows 64 bit only
- _WIN32 is defined by the compiler on Windows 32 and 64 bit.
- _WIN64 is defined by the compiler on Windows 64 bit only.

If my understanding is incorrect, please correct me.

If I want code that only runs on Windows (32 or 64 bit), I should
check if _WIN32 is defined.

The FileAttributesPlugin has a method with "<option: #WIN32>", which
causes it to only be compiled on Windows 32 bit, while I also need it on
Windows 64 bit.

"<option: #_WIN32>" isn't recognised, so the code is never generated,
and I couldn't figure out how to have #WIN32 OR #WIN64.

What's the correct solution?

Thanks!
Alistair

Sorry not to have got to this sooner, but the support is in there now. So by all means use <option: #_WIN32> now.

Thanks! I'm focusing on the in-image integration at the moment, but
I'll definitely change this back to using the option: pragma.

Cheers,
