I don't know what anyone else is expecting, but what I've been doing is using
a currently-supported version of both the OS and the compiler. With open
source, it becomes a bit murkier if only because we know that there will be
many users out there with slightly outdated versions even if those working on
the software no longer support that version, e.g., the perl 5.10.1 that comes
with AIX 7.
Yes, there are also many users using AIX 5.1/5.2 which are out of support, and
there will be many users of AIX 5.3 for some time to come, despite it going
out of support as of Tuesday. But, for some reason, my gut says that it's
easier to justify perl's focus on current versions of AIX and xlC than the
latest version of gcc and however far back they go. Maybe that's wrong, it
may just be my impression that commercial vendors offer longer-term support
than open-source teams, so someone who got AIX 6.1 the month it came out and
put gcc on it may find that their OS is supported with regular fixes plus
security fixes, but not their compiler.
So, if it's reasonably modern, IMO, it should be okay. Of course, if
something does go wrong with an old gcc release, eliminating that old gcc as
the problem may become necessary, despite MJD's maxim #11907.
Personally, I'd use what you had available and only upgrade if there becomes a
reason to. I'm more or less expecting it to just work, and then you save
yourself a bunch of extra hassle.
