+Subject: xfsprogs: do not redeclare globals provided by libraries
+
+In each of these cases, db, logprint, and mdrestore are redeclaring
+as a global variable something which was already provided by a
+library they link with.
+
+gcc now defaults to -fno-common and trips over these global variables
+which are declared in utilities as well as in libxfs and libxlog, and
+it causes the build to fail.
