But what is the reason? I think it severely limits the use of
typedef'ing functions, which could be otherwise very useful:

typedef void cntrlc_handler(void);

main()
{
	cntrlc_handler c_handler;

	signal(SIGINT, c_handler);
}

It is a shame to be forced to define c_handler again:


void c_handler(void)
{
   ...
}
