[IGSTK-Developers] Warnings in VS.net 2003

[Julien Jomier]

Patrick, Luis,

Sorry for the late reply (you might have discussed this issue already at 
the T-Con).
Andy and I have been working on a dashboard for FLTK for the past 6 
months: http://public.kitware.com/dashboard.php?name=fltk
The best way is to submit bug reports and patches to the FLTK bug 
tracker: http://www.fltk.org/str.php

It's correct that FLTK folks don't really care about warnings but they 
are usually good at fixing them (and 1.1.6 was really bad in that 
sense). Hopefully the dashboard will help.

I should be on the T-Con next week,

Julien
