Calling all powerpc(32) users,
Attached is a patch which changes the size of time_t from 32-bit to 64-bit
on powerpc. ARM and MIPS already use 64-bit time_t, the only other holdout
is i386, which cannot be changed. I want to get this in soon so there's
plenty of soak time before 12 is branched. It works well enough for my
cases, but I want others to poke, prod, and try to break it. Especially
try your favorite ports builds, and make sure things still a) build, and b)
work as expected.
Almost forgot, too... With powerpc64 users, the compat32 has been updated
as well, obviously. So, some testing of that is needed, too.
- Justin
