Sigh. It's been awhile since I've programmed in C, but I'm SURE that
you can have a function whose scope is purely within another
function. You simply can't do this in C.

Yet here I have a program which compiles without a peep under
gcc4.2.1 (with -ansi -Wall, no less), AND runs correctly, but which
icc (10.1.015) won't touch with a ten-foot-pole:

=====begin sample program=====
#include <stdio.h>

int main()
{
int sub1()
{
printf("1");
return(0);
}
int sub2()
{
printf("2\n");
return(0);
}
/* start of main */
sub1();
sub2();
}
=======end sample program========

I don't see anything wrong with this. Nevertheless, icc aborts the
compilation with the fatal error

testit.c(6): error: expected a ";"
{
^

It doesn't like the opening left-brace of "sub1".

Now, I've read this group before, and I know I'm going to get reamed
for such a simple question, but: what's wrong? And why does one
compiler pass it and the other doesn't?
Which one takes it? Must be a non-conforming one then.
Ah, I see, gcc. Add -pedantic to switch off that non-standard extension

This is in openSuse 10.3 on a 2.5GHz core 2 duo with 3GB RAM (though
none of that matters).

Thanks in advance,

Bye, Jojo
