FYI, while testing my most recent changes, I ran across a recent
compiler bug. To reproduce: using the current compiler, do a fresh
compile from sources. Then use that compiler to do another fresh
compile. The second compilation hangs during the compilation of
"cref/anfile" (the very first file to compile). The problem appears
to be that the compiler is running map over a list of items, but that
the list is circular.
Yikes. And I thought that my two-iteration build for testing before
pushing would suffice, but it didn't turn this up, because I'm
starting with an image made 2009-02-24, building the current sources,
and then building them again using the newly built compiler. I guess
I'll bump that to a three-iteration build and see what happens.
