It shouldn't.  If I write:
	int foo(int x)
	{
		return (log(x));
	}
without explicitly declaring any prototype for log(), gcc should
assume a declaration "int log(int);".  Arbitrarily deciding that
the declaration should be "double log(double);" breaks K&R C and
C90 programs.

It seems that gcc is diverging more and more from the ISO standards.
