For scripting mode it would be handy to be able to compile from stdin,
btw. Something like this, but perhaps without using /dev/stdin but 0
would seem to be appropriate.

$ echo -e "#include <stdio.h>\nint main(void) {printf(\"%s\", \"Hello,
world.\\\n\");return 0;}" | tcc -o no -  && ./no
Hello, world.

Sounds useful?
