I usually bootstrap the weekly snapshot of gcc 4.4
with the Intel C compiler.

This usually works, but this week snapshot 20090306 didn't.

There seem to be some fun & games with linking together to
make cc1-dummy.

Given the number of function with names starting with "cloog", I'd guess
that something has gone wrong in the detection of the correct location
of the cloog libraries.

Using -L/lib for -lcloog looks deeply suspicious to me.
Even more so, -L/lib for -lppl_c and -lppl.
