I didn't want to get into this argument, as there are companies that 
have valid reasons not to use DWARF2 given the current implementations, 
particularly those compaonies that end up with 1 gigabyte with stabs 
info, and 5 gigabytes with dwarf2 info, or something like that.

However, I was going to ask whether the cost of *adding* more features 
to the STABS implementations in gdb and gcc is worth the future 
maintenance cost at this point in the life of STABS.

And, more importantly, in the process of being fixed.
