[webkit-dev] Fix for Vector::m_inlineBuffer alignment?

[Paul Pedriana]

Well the proposed solution in 
<https://bugs.webkit.org/show_bug.cgi?id=16925> doesn't work, as VC++ 
doesn't accept that syntax. And the solutions in 
<https://bugs.webkit.org/show_bug.cgi?id=19775> whereby a uint32_t or 
uint64_t buffer are made don't work for larger types and use more memory 
than necessary. They might be useful as a fallback for compilers that 
don't support alignment directives, though the primary implementations 
of every compiler that I work with (GCC, VC++, CodeWarrior, EDG, SN, 
IBM) support it.

I'll make a patch and attach it to 
<https://bugs.webkit.org/show_bug.cgi?id=16925>, if that's OK.

Paul
