Suppose, in C, that one is in a for loop or a while loop, and
some unusual situation arises under which processing cannot continue.
The break statement allows one to conveniently handle such cases.

But, really, folks, what is the difference between

...
switch(x)
{
  case a: ... break;
  case b: ... break;
}
...

and

...
case foo is
  when x => ...
  when y => ...
...

(I think I remember my Ada correctly... if not, please, it's close enough)?

The control structures case/when have to be terminated somehow.
In Ada, it is terminated by the next when statement.  In C, it's
terminated by a break statement.  Just deal with it.  

Personally, I've found some nice uses of NOT putting a break in
a switch statement, when I have two similiar cases, but one has a
little bit more processing that needs to be done...

This is a *C* newsgroup.  Why talk about the merits and disadvantages
of Ada?  Take it to comp.lang.ada, if there is one.  People like
C.  Who is anyone to tell them (including me) that their opinion is
wrong, or that their preference is wrong?

Give it a rest.
