Yes, this is normal.

This is normal.

No, you don't.  gcc knows about both directories.

This is normal.  The binaries are identical.  You should
probably ignore the directory with the short names, and
use the one with the long names, but that's just a matter of taste.

Yes, you're looking too hard for order.   Embrace disorder :-)

You're not being very clear here.  How did you compile gdb-6.0?
Perhaps you didn't compile it correctly for cross-debugging.

Bill used to have some FAQs there.  Guess he removed them
when he converted to Drupal.
(Bill, could you at least add a link to crosstool?)
