When were trigraphs added?

(I am just curious, I have no idea how common your parent's comment is in real life.)

Pretty sure gcc doesn't enable trigraphs unless you pass a command-line option to do so (and maybe it's included in -std or -ansi or something like that).

i've had issues with templates, but please forgive me if i don't provide specifics because it was ages ago. i've stopped doing C++ long before auto was even proposed so can't comment on that.
