Not at all!!! -fpermissive can (in weird cases, agreed) change code
generation. I'm pretty sure you don't want to risk that only to silence
an error.
What? That doesn't make any sense. And it is certainly not documented
in the manual. I will be very interested in an example, no matter how
weird or uncommon.
Uhm, I might be confusing it with -ffriend-injection (which is in some
sense more permissive than -fno-friend-injection).
Reading "in some case name lookup will not be standard conforming" in
bkoz's document at http://people.redhat.com/~bkoz/porting_to_gcc43.html
added to my confusion.
