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. Unfortunately this version does not build on windows, so for now, xrootd has been disabled. I do not believe anyone uses xrootd from windows anyhow. We will activate it again, when we're able to build xrootd. Probaby when we move to ROOT v5.24.00 and can hopefully use xrootd out of the box.
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
