Caveat: I don't have a Solaris 2.6 machine to test against.  The
following is FYI.

I'm not sure how well-supported an interface _LARGEFILE64_SOURCE is (as
opposed to _LARGEFILE_SOURCE, e.g.); <sys/feature_tests.h> refers to
_LARGEFILE64_SOURCE as a "transitional interface".

The lfcompile(5) man page (Solaris 8 version attached) provides the
supported method of compiling apps with largefile support under Solaris.
Perhaps getconf(1) should be used to define the correct flags (rather
than guessing at which macros need to be defined) to ensure
compatibility with current and future releases of Solaris.

Dan Astoorian               People shouldn't think that it's better to have
Sysadmin, CSLab             loved and lost than never loved at all.  It's
djast at cs.toronto.edu        not, it's better to have loved and won.  All
www.cs.toronto.edu/~djast/  the other options really suck.    --Dan Redican
