tools/fnt2fon is flagged in the janitorial page "IgnoredReturnValues". This page is outdated, but its content is still valid for fnt2fon, which ignores a number of return values.
I don't think that's worth fixing, the warnings are essentially useless, it just makes the code uglier. There may be a few legitimate errors in there, like checking the fopen() result, and those could be fixed; but please don't add checking to every call that gcc complains about.
