+    Call malloc, not xalloc
+    
+    One call in xfstrans.c used xalloc - everything else already had malloc.
+    Fix this so it won't break when Xtrans stops defining xalloc to malloc
+    for us.

+    Use config.h for autoconf output now that there's no conflict
+    
+    Now that os/config.h is gone, no reason to special case and have
+    xfs-config.h for the autoconf generated header.

+    
+    The only file that needed the only remaining definition was config.c,

+
+    Make CONFIG_ERR_* values be strings instead of indexes in ConfigErrors array
+    
+    Allows gcc to check printf format strings instead of just giving warnings.
+    Since these #defines are only used in config.c, define them directly there,
+    instead of in the config.h header that no one else includes.

+    Add _X_NORETURN to declarations of functions that exit
+    
+    While you might think FatalError() also should have _X_NORETURN, if
+    you add it, you will find that gcc warns you that it does indeed
+    return when built with syslog support.   Why syslog makes all fatal
+    errors become non-fatal is an excellent question to ponder...
