Comment 5 for bug 245645

GDB is a debugger, so if your linux install is i386, you don't want the 64 bit package. Does that mean you are compiling for 64 bit on your 32 bit machine? I've never done/tried this, but if you are, as long as you have the code libraries you shouldn't need anything for GDB in 64 bit since you can't actually run it. If I am misunderstanding or just wrong, please let me know.

Basically what this comes down to is you don't typically want 64 bit packages available for 32 bit installs.
