(I wasn't confroning you personally, if that's how you interpreted it.)

How often do end users actually see these errors?  And if they
do, they're probably curious enough to actually want to see them and
perhaps they'll even report them to the developers, when they do.

Knowing that there are problems with the code and lying about it to the
people who compiles it doesn't seem right to me.  I use the following
set of -W's for all my projects: -Wall -W -Wwrite-strings
-Waggregate-return -Wmissing-prototypes -Wmissing-declarations
-Wnested-externs -Wundef -Wpointer-arith -Wcast-align -Wshadow -Werror.
This makes sure that I know of any potential problems that the compiler
was smart enough to pick up.  It won't make my code bug-free, but at
least it'll make me sleep better at night, knowing that I tried my very
best,
