Under "Intel 386 and AMD x86-64 Options" are listed several different
parameters one can give to -march, such as i386,i486,pentium,prescott,etc. For
AMD64 users the special options -m32 and -m64 specify whether to build for 32
or 64 bit environments. Aren't both these options redundant? If you're building
on an amd64 then the default target architecture ought to be 64-bit, and if you
specify -march=i386 then presumably you want 32-bit code...
