[lwip-devel] [bug #52611] Incorrect use of ctype macros?

[Mike Kleshov]

Follow-up Comment #5, bug #52611 (project lwip):

I don't understand this. If it's wrong in the caller, why the cast to int in
the first place? To fix compiler warnings? Shouldn't they be fixed in the
caller?
Besides, where does it say that lwip_is<whatever> macros must behave just like
standard ctype macros? If you are willing to fix compiler warnings this way,
you might as well do it in a way that insures that nobody has to 'fix the
caller'.
