AVR-Chat

I have purchased an ATMega16 based board to connect a project to the Internet.
I'm attempting to compile my first real embedded program.  The example code that
came with the board was written for ImageCraft's ICCAVR Pro C compiler and I'm
currently converting it to WINAVR.  I'm trying to digest all the documentation
but my unfamiliarity with both compilers is hampering me.  If you would indulge
me with a couple of questions:

I have two functions that are being flagged with the following warning:

"function declaration isn't a prototype"

One is declared:

void overrun()
{
...
}

... and the other ...

void init_ASIX88796L()
{
...
}

Both functions are declared prior to their first use and there are other "void
funct()" functions which do not cause warnings.

- What exactly is this trying to tell me?
- Where can I find descriptions of the various warnings and errors from WINAVR?


I came across a couple of occurrences of:

    do{
        ...
        result = byte_read & RDC;
    }while (result = 0);

Shouldn't "while (result = 0)" be "while (result == 0)" ?


If I understand it correctly I should convert the following code:

#pragma interrupt_handler USART_RX_interrupt:iv_USART_RX 
...
void USART_RX_interrupt( void )
{
...
}   

... to ...

SIGNAL(SIG_USART_RECV)
{
...
}   


Are there general guidelines available on the Internet concerning converting
ImageCraft's ICCAVR Pro C code to WINAVR?

Thanks in advance for your help.

Cheers,
