Hi , 
   I am using gcc to cross complile for 68k on a Sun. 
gcc --version says it is 2.7-96q1.
    Due to some error in cut and paste , I had a piece of code
similar to 
    void foo()
    {
      void foo()
      {
          int i;
        
          some_function(i);
          printf("hello world\n");
       }
     }

   And gcc compiled it just fine. Is this a bug? If not , what 
is happening? 

Also , due to another cut and paste , a newline got inserted in
a string constant and gcc did not complain , but took it as a 
\n in the string at that point. This seems inconsistent with
Microsoft C. Example
   #define WORLD "hello
          world"

Thanks

No, it's not a bug. Your code is correct so why do you want gcc to
complain ?
Teh second declaration of foo hides the former one and becomes a local
function of the former function foo. There is nothing to say about that.
It's up to you to keep in mind when you call "foo()" what is the
function wich is known at the line you make the call.
It's the same thing when you make :

int i;

void foo()
{
	int i;
	i=1;
}

main
{
	i=1
}

the second "i" hides the first one and becomes local to the function
foo.
