i am using gcc-multilib, gcc-fortran to prevent my system from upgrade.
so i have to remove gcc-fortran, then everything works fine.

It's simply because the multilib version hasn't been updated to pkgver 2 yet. You could always use gcc-fortran-multilib.

Using multilib is all or none...

pacman -S gcc-multilib gcc-fortran-multilib

at first, i was using gcc, then i need gcc-multilib for some reason,
so i have installed it, using it for now,

what i don't understand is why gcc-fortran was not removed at the time.
and i don't need fortran at all. time is lack for better programming language such like lisp, c compiler, clojure, scala, nimrod, etc.etc.

Allan, i agree it should be like that but the reality is different.

afaict gcc-multilib provide all functionality that gcc-libs does PLUS the 32-bit compiled to work in x86_64 environment stuff.

So all gcc-multilib pacakges provide their non-multilb counterpart.
From a technical point this is correct, but the downside is that it's possible to mix multilib with non-multilib versions on the same install .
That mix possibility is what causes problems.

I can think of some ways to solve this :

differ gcc packages between i686 and i686 :
build gcc for i686 as it is now
for x86_64 only provide gcc with multilib functionality
(basically this would mean renaming gc--multilib to gcc and moving it from multilib repo to core, along with necessary makedepends).

This would mean gcc multilib functionality is forced on all x86_64 users, doubt if that is a good idea.

alternative :
Add a conflicts clause for gcc-libs-multilib to all gcc non-multilib programs.
example : gcc-fortran would have conflicts=(gcc-libs-mutilib)

That means users have to choose between multilib and non-multilib, but doesn't force multilib on all x86_64 users.
