Try a different preview kit.  I'm told that some of the MIPS preview
kits were updated for 3.0 and some weren't, and that's all I know about
that.

You _HAVE_ looked at crosstool, right?  Which does all of this, and
does work?

Come on, think.  Glibc 2.3.2 was released before GCC 3.3.  It built at
the time; if you use GCC 3.2 that will compile.  If you want to use GCC
3.3, then use a newer CVS snapshot of glibc.  Which I recommend, but is
still not for the faint of heart.  If you're just trying to build a
kernel as you said later, why are you building glibc anyway?

Google will be delighted to explain the controversy of
-finline-limit-10000 to you.  Or use crosstool :)
