Compiler warnings should are important, i agree, but they are not errors. As long as they don't result in real errors in the application they can at least be partially ignored. But if we had to fix all the compiler warnings of all our packages in our distribution we'd probably have to hire tons of new people. :-) Thanks for reporting anyway but i'm closing it as NOTABUG as it is a warning, not a bug :-). If i ever have some spare time i'll be looking at it again. Read ya, Phil
I'm sorry to hear that even though I'm providing exact file names and line numbers and describing the fault as best I can, you are unwilling to fix these minor problems.
