Your sample is still non-compilable (you should strive to post
complete compilable test cases), but easily fixed with 2 typedefs.

The sample also compiles fine (gcc-3.4.6, 4.1.1) but with '-Wall'
gives a warning:

  union.cc:21: warning: 'nString::<anonymous union>::strLen' will be 
initialized after
  union.cc:19: warning:   'ushort nString::<anonymous union>::<anonymous 
struct>::localStrLen'
  union.cc:28: warning:   when initialized here

Note that this is completely different from the warning in your
original test case (at the start of this thread).

To eliminate the warning, swap the order of initialization:

inline
nString::nString() :
    string(0),
    localStrLen(0),
    strLen(0)
{
}

Since you shouldn't actually care about either 'strLen' or
'localStrLen' when string == 0, both of these initializations appear
to be unneccessary.
