It breaks any GCC, since:

(a) gcc has /usr/local/include on its default include search path, and
(b) specifying -I /usr/local/include means it is on the path twice, so
(c) #include_next doesn't work properly.

At least, that's my recollection of the problem (which was many years
ago on IRIX). Take it with a grain of salt, since my memory has
recently been shown to be faulty. :-)
