I'm glad it has explicit integer sizes. I use C99 standard types often. I don't have much of an opinion on the explicit bool type although I hope it has a defined size.
I'm surprised it allows fall-through in a switch statement. I thought people hated C in that you needed a break keyword to prevent it.
It is interesting that its compiler is also the build system but I see that being a problem if you need to mix languages. For example: I have a Lua script I want to embed into my code. Doing this is simple with make and hard with every other build system.
Windows/Cygwin support means I will look at building this.
1. Find (recursive searching upwards in directory tree) & Read a recipe file (a file for the build system)
2. Either start building all targets or just some, depending on the command-line arguments
3. Build the targets. Output is C (basically complete) or LLVM IR bytecode (like 25% complete).
4. Write a makefile for said C files
5. Compile with default C compiler
so mixing languages works with a little hacking.
I am the author of the Windows/Cygwin support/port, so in case anything doesn't work (especially since the compilation of LLVM is often a horror in Cygwin), let me know and I will see what I can do.
