Experimenting with squash

I am trying to squash 5 commits till date but it didn't happen for
the commits that are dummy. I had created dummy commits to check this feature
and it did recongnize them and didn't allow to squash them. It was only when
I asked git to squash commits that weren't dummy, it allowed me to rebase them.

Dummy build_script file created.

This is the first checkin from my Mac box.

Testing in posix compliant mode
