1) a library that lets you compile C code within a process, relocate it and execute it. This is rather faster than shelling out to run gcc to create a shared object and open it using dlopen.
2) an awesome 2004 demonstration where TCC was used as a boot loader. Take the Linux kernel source (slightly modified to remove some of the gccisms), add TCCBOOT and reboot the machine: as part of the boot process TCC recompiles the kernel and the continue to execute the freshly compiled kernel -- all in 15 seconds: http://bellard.org/tcc/tccboot.html
How would you like to have a REPL for kernel development, like on the Lisp Machines? (Yes, that's a rhetorical question!)
Take TCC with your point 1 above. Mix it with the ideas from Schemix ( http://abstractnonsense.com/schemix/ ). Now you can iteratively development a kernel driver!
I hacked on Schemix a while back, updating it to 2.6 module system (unfortunately lost the source code before it got uploaded). It's a seemingly great idea but what good is scheme code if you have to rewrite in a different language for the final version?

TCC has two even more cool things:
1) a library that lets you compile C code within a process, relocate it and execute it. This is rather faster than shelling out to run gcc to create a shared object and open it using dlopen.
2) an awesome 2004 demonstration where TCC was used as a boot loader.

I really love Fabrice, but "TCC" will, forever, remain Turbo C, not Tiny C.
DOS weenie pride!
Ctrl+F9 ftw.
