I thought Quartus doesn't support the 2008 version. Here's what Altera Support said:

---

i checked in the database, the fixed_pkg is yet to be supported in qpro version or in qstandard version. and i had try one of the design using

use ieee.fixed_pkg.all;

but it does not work in qpro or qstandard. i do not have the detail when it will get support. however, i will go ahead and request the enhancement for this support.

I had to use the 1993-compatible version in my Quartus project by compiling it into the ieee library. But I'm not sure what version of fixed_pkg my ModelSim project is using.
