Regular users like me don't read this page and probable can't be realistically
expected to read it.
So, if the situation is really as bad as mentioned there, it should be
mentioned in the places that users do read.
Like these:
https://gcc.gnu.org/onlinedocs/gcc-5.3.0/gcc/Function-Attributes.html#Function-Attributes
https://gcc.gnu.org/onlinedocs/gcc-6.1.0/gcc/Common-Function-Attributes.html#Common-Function-Attributes
