>Description:
Can't compile a C++ file using STL map #include directive
#include <map>
When a directory named map exists in the include path somewhere.
We get the following compile error:

main.cc:2: directory `../map' specified in #include
>How-To-Repeat:
Create a directory map in the parent directory that code is
in (ie mkdir ../map).

Compile this file with:
g++ -I.. -I. -g -c main.cc
