Was this the lib/*_tab.c files?  This has been fixed in the 2.3.x
series.  Btw, you may want to try 2.3.x instead since it has been
improved and cleaned up in many ways.  Only the openpgp stuff is
somewhat unstable, the rest is assumed to work perfectly.

What exact warning did you get?  I'll see if I can trigger the same
warning.  Possibly it is only emitted in your particular environment.
