Our rule of thumb [1] is to provide gnulib support as long as vendor support
exists.

According to Wikipedia [2], the vendor support of AIX 5.1 ended in 2006,
the one of AIX 5.2 in 2009, and AIX 5.3 is still vendor-supported.

So I have no problem with dropping AIX 5.1 and 5.2 from the list of platforms
I test on, and use AIX 5.3 instead. It has openat().
