I was able to compile umbrello-1.1-rc1 (stable) with flex-2.5.25 by
fixing a bug in umbrello-1.1rc1/uml/classparser/tokenizer.l in which
there was no declaration of `yywrap'. In C, this is ok, but C++
disallows implicit declarations. The fix, which is in the FAQ (in the
flex manual), and which can be found by searching for `yywrap' in the
flex manual, is to specify %option noyywrap (or --noyywrap). -John
