1. make sure you're not compiling with debug info (-g) on.

2. you can just use a bit editor to stomp on those names in the executable 
(replace them with XXXXX or whatever). The exe files are not checksummed, so 
this should be straightforward.

3. rename your sensitive classes to obscure names, then alias them to a readable 
name. The alias name shouldn't appear in the executable:

     class CXX97ASDFXX { }
     alias CXX97ASDFXX mySensitiveName;
