OK - I think I found the answer which is that \b is a GNU extension not
recognized in cygwin.

So, I guess the question now is there an alternative way of recognizing word
boundaries?

In particular, I am trying to match a process id where $proc is a list of
one or more processes (awk'd from ps). 
So, for example, I want to make sure that if $proc="123 456 789" that "456"
matches but not "45"

Perhaps, I could try adding white space as in 
[[ " $proc " =~ " 456 " ]]
but not sure if that will always work.

So, what is the best way to do this without the "\\b" word boundary symbol?
