I found the following on a Google-cached copy of a web page about hacking
into linux systems by exploiting "find ... -exec rm {} \;" as run by cron.
It would appear that faccess() and faccessx() [and by extension probably
accessx() as well] are strictly IBM-isms.

Here is a comparison of some related calls between various OSes:

           Linux*    AIX 3.2   Sunos 4.1.3   Solaris 2.5
