Few places still maintain genuine i386 support—I don’t believe the Linux kernel does, for example. There some important features it lacks, such as CMPXCHG. Nowadays Debian’s i386 is actually i686 (Pentium Pro), but apparently they’ve decided to introduce a new “i686” architecture label to denote a 32-bit x86 ABI with a 64-bit time_t.
Also, I’m sorry to have to tell you that the 80386 came out in 1985 (with the Compaq Deskpro 386 releasing in 1986) and the Pentium Pro in 1995. That is, i686 is three times closer to i386 than it is to now.
