Subject: [PATCH] Added Lesstif-specific suppression of harmless but annoying
 warnings generated by non-production versions of the library. Developers can
 see the suppressed messages by adding -DDEBUG_LESSTIF_WARNINGS to their
 compile flags. So far, I've added 3 messages to the suppression list, but the
 list can easily be extended if more of these messages show up.
