12 It has always been that way for packages in the same slot. 4.5.3 and
13 4.5.4 are both in the "4.5" slot. I think you're confusing
14 patch-version upgrades with major and minor-version ones. If you emerge
15 GCC 4.6.3, your 4.5.4 version will be kept.

17 If you really wont to keep multiple patch-versions, then you must set
18 the "multislot" USE flag for GCC. But unless you have a reason to do
19 that, and it seems you don't, there's no reason to have multiple such
20 versions installed.
