I'm assuming that the intent of a "one line" program is that it is one line
of code, not including the header and variable declarations.  The only
other assumption made is that the source has a ".c" extension to the
program being run.  Otherwise, here's my program.

----------------------------------
#include <stdio.h>

main (argc, argv)
int argc;
char *argv[];
{
  FILE *fp;
  int ch;

  for ((strcat (argv[0], ".c")) && (fp = fopen (argv[0], "r"));
      (ch = getc (fp)) != EOF; putchar (ch) ) ;
}
----------------------------------

Notice, that the code part is only one statement long.  It certainly could 
have been written as one text line, but it would have been slightly less
readable by many terminals.

--------------------------------------------------------------------------------
"If it ain't broke, don't fix it," and certainly don't blame me.
