I guess this is a reference the the "fixincludes"

http://www.gnu.org/software/autogen/fixinc.html

which gcc uses to "fix" header files it does not like. In practice,
I've found the gcc solution to be far from optimal.

I note that the Clang compiler has rejected the fixincludes approach
used by gcc.
