The #include is not in the code for the test but it is in what the compiler 
gets to compile (according to config.log and according to the genereated 
./configure

However the comment seems to indicate that it is not enough in some 
conditions. ("gcc2" is quite vague.)

That is why I have not tested to remove the defintion.

(As for the reason, I suppose that the problem was that the test is done under 
C++ now and not in C anymore. That is the only potentially relevant change 
that I can see form the diff.)

Nevertheless I will try to remove the definiton and see what happens.
