fdatasync and configure on OSX

[Wesley Smith <we...@gmail.com>]

Hi,
I've tried to build apr-1.4.2 on OSX 10.6.3.  I did the usual
./configure and make.  At issue is fdatasync.  It's undefined in the
resulting lib because, as mentioned in the configure files, OSX
doesn't have it:

$ find . | xargs grep fdatasync
./configure.in:dnl ----------------------------- Checking for
fdatasync: OS X doesn't have it
./configure.in:AC_CHECK_FUNCS(fdatasync)

For some reason, the AC_CHECK_FUNCS is failing and in apr_private.h I have:

/* Define to 1 if you have the `fdatasync' function. */
#define HAVE_FDATASYNC 1


I can change this to 0 manually, but configure should be taking care
of it for me.  Is this a known bug?

dunno

check config.log for messages related to fdatasync (probably the 100+
lines including test program starting with the first occurrence of
"fdatasync")
