Are you sure about atoi supporting octal?
AFAICT POSIX 2008 forbids that, and requires atoi to support only decimal numbers.
At any rate, changing that is probably highly unwise, as it might break stuff.

D'oh! You're quite right about atoi(). I meant strtol(), but wasn't thinking straight. strtol() allows you to optionally specify the base=10, but then won't permit 0x... for hexadecimal.
I agree that we can't change it right away. That's why I suggest adding a new prefix, "0o" to be used in the very rare case where the programmer deliberately intends to use octal. That wouldn't break anything, and over perhaps 5 years, people could migrate.
