You are mixing version numbers. DJGPP is and was 2.01 (although there
is a 2.02 alpha, but you don't want to knoe about that). GCC exists
with version numbers like 2.7.2, 2.8.0 and 2.8.1. It seems like you
have downgraded your compiler, GCC.

GCC version 2.8.x has pentium support and knows about -mpentium.

Exact.

Because you have downgraded, it may seem this option has disappeared,
but it really was new in 2.8.x i think.

If you like it that much, maybe you should reinstall GCC 2.8.1.
