Subject: Fixed some alignment problems on sparc
X-Git-Tag: debian/1.0.1-1~7
X-Git-Url: http://git.debian.org/?p=pkg-webkit%2Fwebkit.git;a=commitdiff_plain;h=11c220f6d31898a7a1dfafd5d96619fefe6ba597;hp=1db04c3a5c8c3e9c990b93836d5bb09d43a47921
Fixed some alignment problems on sparc
(and some that might occur on arm, too).
Some compiler warnings about alignment remain, but I don't know if they are
a real problem yet.
