I'd also vote to retire '-p4', but we might need something like -sse2/3/3e
or -mmx/-3dnow/-enhanced3dnow that kind of stuff.

Pentium 4, -mtune=pentium4 (or older switch of -march=pentium4) in gcc,
probably means MMX, SSE and SSE2 instruction set support. It's the default
in ifort if I remembered it right.

Best,
