I fear that fdatasync() is currently some kind of a ghost on Mac OS X; I've asked on the darwin-dev list, should someone have definitive information.

On the other hand, autoconf et alii may come with their uglinesses as well. ;-)
Here, AC_SEARCH_LIBS seems to fall in the trap by defining a prototype for an existing yet very ambiguous symbol.
Looks like that AC_TRY_COMPILE could avoid the problem in that precise case.
Now, my knowledge about those matters nearing zero, I'm really *unable* to tell whether the latter would be safer under any circumstances...

HTH,
