We actually have a lot of code that works for this as this is mostly an update to get C++ features in C, however the main workload I see being a problem will be #embed, which is a preprocessor addition. I am using a draft that shows all the features added as well.

Edit: not sure what milestone this belongs in, just not in the current one, maybe 4th milestone would be a good idea?

yeah if it is really mostly C++ stuff ported to C it will be fairly easy, although, we might want to consolidate the C compiler version checking into a single variable... #embed doesn't look hard, I write programs that generate code like that all the time. We can resurrect the AES example I had and move the encryption/decryption tables into binary files as a test program lol...

I'll go ahead and put it in milestone 4 😄

I'll be working on this for a while. The big thing left is _BitInt but there are a lot of smaller issues as well...

I'm through the BITINT stuff and worked on a bunch of the more piddly stuff. I have two or three issues left to do then we will be mostly done other than the #810
