This hack hard codes gcc version 4.2.3 and target triplet. This hack  
opens door for multiple paths (each one for a unique combination of  
gcc version # and target triplet. Which could turn this into ugly hack  
very soon.

A better alternative is to use a clang configure time option that  
allows you to capture "/usr/lib/gcc/x86_64-linux-gnu/4.2.3/" as  
GCC_HEADERS_PATH and then add GCC_HEADERS_PATH/include here. A clang  
command line option to do the same would also work here, I guess.
