Hi Erik,

thanks for reviewing and sorry but I've already pushed this yesterday evening before leaving because I wanted to fix our nightly builds.

I agree that the long line in jdk-options.m4 is ugly and I put it on my TODO list. Taking into account the current cadence of AIX build fixes I think it wont take long until I'll have to revisit that file anyway :)

Hello, Looks good. My only minor nit is the rather long line in jdk-options.m4 that I would appreciate if it was broken up (no need for respin if you do). /Erik
