Why can't Mathematica integrate thrice a piecewise defined function? 
Here is what I mean:

This is a step function:
It can (of course) be plotted and integrated. Then let:
f, as well as h, can be plotted and if I put
then g can be plotted, but any integral (definite or not) that I attempt
to compute about g leads to an error message (though g can be 

Am I doing something wrong somewhere? Thanks for any help.
