Question about gcc-4.4.4

[Pavel V Samsonov <samsonov@xxxxxxxxx>]

Good day!
I use gcc-4.4.4 to compile C code. When I use glibc functions and miss
include headers, gcc still compile code. For example:


/*#inclide <stdio.h>*/
int main()
{
	printf("printf");
	return 0;
}

This mean that gcc not verify presence of function "printf" before
linking stage? Where I can read about this?

Thanks!
