It was a user defined function. The problem turned out to be where the
function was prototyped. In gcc 4 you can not declare a prototype
within a function body. IE:

void
somefunct(void)
{
void sigio_func();

...
sigio_func();
}

wont work but:


void sigio_func();
void
somefunct(void)
{
....
sigio_func();
}

will work.

Thanks for the reponse
