Hi Guru, 
Do we distinguish between Debug and Releases builds? ( I recall we discussed this before but forgot what was the outcome)
Enabling optimization may cause some issues for the debugger to match the source to the code.
Thanks,
Eitan

Subject: [ovs-dev] [PATCH 2/2] cccl: Enable compiler optimization by default.

There is no 1-1 mapping between gcc's compiler optimization flags and MSVC's optimization flags making the automatic conversions trickier.

This commit adds the /O2 option which is the recommended option for fast code.
