Hey Mahesh,

thanks for working on this. As a small hint from my side, I have the 
feeling there is currently no need to submit the entire OpenMP patch for 
review. You could e.g. start with the patch that adds the (command
line option, but just ignores it. As a next step, you could submit a 
patch that makes  >>include "omp.h" << work (without yet supporting
any definitions, ...)

I think at the beginning it is helpful to start with smaller patches and 
to get used to the review policies. This will prepare you for the
larger discussions with Elli and Co. :-)
