Ahh, that explains it.

Wow, this is a messier tangle than I previously thought. :-)

Is any of this documented anywhere? I think the original bug submitter
filed the bug because according to his understanding of the documentation,
fsync *should* be included when _POSIX_SOURCE is defined. The manpage
*does* mention POSIX.1b; so if what you describe above is actually
documented somewhere, then the submitter should be referred to it, and the
bug should be closed. 


Roasting my brains over a slow fire. Please do not interrupt this process.
