I was having fun with old Golang C code before they started bootstrapping in Go and have found they were using interpunct to separate function names, so I decided to play around with shellscript-like C code to goof around:

        #if 0
        set -e; [ "$0" -nt "$0.bin" ] &&
        gcc -O2 -Wall -Wextra -Wpedantic -std=c11 "$0" -o "$0.bin" -s
        exec "$0.bin" "$@"
        #endif

        #include <stdio.h>

        void runtime·sysAlloc(void);

        int main(void)
        {
            unsigned age = 44;
            printf("I am %u years old.\n", age);
            runtime·sysAlloc();
            return 0;
        }

        void runtime·sysAlloc(void) {
            printf("Hello from C code, %d!\n", 90);
        }
