Um, I have these statistics, but I need to know *exactly* what you want to 
know to be able to give them to you.
There's just too many combinations to make a nice table or something.
Even something like STABS vs DWARF2 has too many combinations because 
it changes with each GCC version, and even sometimes with binutils 
versions.

In general, DWARF2 C++ apps, a lot of it is.
