That might be why back in 1999 - 2002, I was waiting around 1h for each OS build variant of our product, a mix of Tcl and C native libraries, super fast.

It is only basically instant in toy examples, or optimizations completely disabled.

Sqlite is 6 MB and can compile in 2 seconds on msvc.

It's 25 years later, if you are waiting for an hour to compile a single normal C program, there is a lot of room for optimization. Saying C doesn't compile fast because 25 years ago your own company made a program that compiled slow is pretty silly.

Single file C libraries are fantastic because they can easily all be put into more monolithic compilation units which makes compilation very fast and they probably won't need to be changed.

Have you actually tried what I'm talking about? What are you trying to say here, that you think single file libraries would have made your 1 hours pure C program compile slower?

I used to compile sqlite regularly on msvc and it was more than 2 seconds. If this is a measurement it is a recent one with recent hardware.

Sqlite is a single compilation unit for much very different reasons than the header only libraries by the way. It's developed as many different files and concatenated together for distribution because the optimizer does better for it that way.

This was on a 10 year old Xeon CPU.

What difference does that make? What does it have to do with anything? You could develop anything like that.

The point here is that single file libraries work very well. If anything they end up making compilation times lower because they can be put into monolithic compilation units. When I say single file C libraries, I'm talking about single files that have a header switch to make them header declarations or full functions implementations. I'm not sure what you're trying to say.
