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.
cheers,
Oliver
