Gaaah!

I've also been bitten in the past by creating a directory named 'new'.
That caused
  #include <new>
to fail in C++ programs.

Two tricks can help figure these things out:
1. use the -H option to gcc.  This prints out the exact header files used!
2. run the compiler under strace -f -olog, then grep through 'log' for
    stat and open calls.  Works when trick #1 doesn't, e.g. when
figuring out linker
    problems.
