Subject: Mark risalpha() and friends as "const functions"
X-Git-Tag: rpm-4.6.0-rc1~32
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=eb9649dfa9676fcf8117f799db8578b72c805673;p=platform%2Fupstream%2Frpm.git

Mark risalpha() and friends as "const functions"
- they only process integers that are fed to them and no outside data
