Some versions of OS X have fdatasync in the headers but don't include implementations in the standard library. This leads to a compile failure in configure.ac when using AC_CHECK_FUNCS. This change explicitly attempts to compile a file containing a call to fdatasync and properly sets the AC_CHECK_FUNCS flags depending on the result of compilation.
