Any reason why
os.path.normpath(a).startswith(os.normpath(b)) doesn't do the trick?

Except for the trivial type, you mean?  That depends on whether "c:\foo" 
should be seen as a subpath to "c:\foobar" or not.  I'd probably go for 
(also untested):

def issubpath(a, b):
    def fixpath(p):
        return os.path.normpath(p) + os.sep
    return fixpath(a).startswith(fixpath(b))
