[HACKERS] Could turn on -O2 in AIX

[Zeugswetter Andreas SB]

but, there is eighter an optimizer bug or a code bug in nabstime.c
leading to regression failure in abstime, tinterval and horology.
The rest all passes.

Does anybody see similar behavior ? It is a little sad, because the 
optimized code really runs a lot faster and those are somehow 
obsolete datatypes.

PS: I have a patch in the works that fixes the runcheck problems for AIX 4.2 and up
that I would like to see into 7.1, maybe tomorrow.
