It appears that _ALL_SOURCE gets defined in the /usr/include/standards.h 
file.  If we could #define _ANSI_C_SOURCE or _POSIX_SOURCE, it appears 
that it would eleminate _ALL_SOURCE.

$ cat t.c
#include <stdio.h>
#include <stdlib.h>

int main()
{
         printf("hello, world\n");

#ifdef _ALL_SOURCE
         printf("hello, again\n");
#endif

         exit(0);
}

$ cc_r t.c

$ ./a.out
hello, world
hello, again
