Yep, these are what the gcc-guys call 'repetition codes'. 

There used to be a bug in the gcc's c++-mangler with respect to these 
repetition codes for array types that causes problems with the symbol 
mentioned by Simon. 
I remember having to patch gcc-2.95.3 to deal with this (aka: to actually 
mangle the names in the way the older compilers did in order to match what 
lives in libbe.so).

I suppose Ingo has not applied the respective patch 
(beos-specific/name-mangling.patch), as it probably doesn't go down well 
with gcc-4's completely different and all new C++-parser >:o/

Ingo, please tell if I can give you a hand on this.
