Fermi Patches
This is a GLAST/Fermi-specific release in that we replaced the default version of xrootd included in the build, to use a patched version of xrootd client. See JIRA: https://jira.slac.stanford.edu/browse/GXR-56
Also applied a patch by hand for gcc 3.2.3, according to the ROOT Forum discussion: http://root.cern.ch/phpBB2/viewtopic.php?t=7294&highlight=utils
Applied a patch by hand for Minuit2:Here is Lorenzo Moneta's description of the change:
If you can't move to version 5.23/40, you could eventually just apply the simple patch to fix this bug.
It is just a one line change in one file, see below
