Are there cases when for example -march=pentium3 would not be

If you're building something that you wish to run on any x86 processor?
Well, that's why they're called compiler _options_.
It's easier for the user of a code (or a configure script) to use
"-march" or "-O4" or whatever. I was curious as to why there isn't a
standard flag in gcc.
