    __BASE_FILE__ does this. It expands to the thing which you
    typed on the `gcc' command line.

    bix:/home/morton> cat a.h
    static inline void hello(void)
    {
            printf("%d at %s\n",__LINE__,__BASE_FILE__);
    }
    bix:/home/morton> cat a.c
    #include <stdio.h>
    #include "a.h"

    int main()
    {
            hello();
            hello();
            return 0;
    }

    bix:/home/morton> gcc -O a.c
    bix:/home/morton> ./a.out
    3 at a.c
