xfsprogs-2.7.18 (16 May 2006)
        - Fixed a case where xfs_repair was reporting a valid used
          block as a duplicate during phase 4.
        - Fixed a case where xfs_repair could incorrectly flag extent
          b+tree nodes as corrupt.
        - Portability changes, get xfs_repair compiling on IRIX.
        - Parent pointer updates in xfs_io checker command.
        - Allow LDFLAGS to be overridden, for Gentoo punters.
	  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Back in 2006 we added the ability for LDFLAGS to be overriden
specifically because Gentoo users wanted it.

Yup, but Gentoo wanted it both ways, and so we gave them that
capability.  And now you're complaining that Gentoo users can shoot
themselves in the foot with it.... :/

Just pass your special CFLAGS/LDFLAGS to configure like the rest of
the world does and everything will work correctly.

Cheers,

Dave.
