2. Download the gdfa-assignment.tar.gz tar ball. Untar it.
3. Patch the newly extracted source with the patch-gdfa-for-gcc4.5.0 patch
file
4. This will add gdfa to the code, enabling two data flow analyses: 
Availabe Expressions and Live Variables.
5. Create a new build directory and build cc1 for this.
6. Read the header comments in the .c files provided and analyze the output of
gdfa on these input files.
