Hi!
I keep seeing a -Wsign-compare warning from GCC 4.7 here,
alloc_count is const int = 16, but length () method returns unsigned.
Perhaps GCC 4.8 folds it to 16 early enough for the -Wsign-compare warning
(might be related to the sizeof changes), but still I think it doesn't hurt
to fix this up.
Changing alloc_count to unsigned would leave to other -Wsign-compare
warnings, because i is signed, ...
Ok for trunk?
