New bug in build process

Unfortunately, no, that's not the case--I was doing a fastdebug build
explicitly (make fastdebug_build DEV=1).

I'm primarily interested in the debug builds because then I have symbols and
can do a lot better exploratory spelunking in tools like debuggers. Besides,
as I spelunk, I'll want to make some source changes (just to play around or
display information), and a lot more info is present in debug builds than
product builds. Frankly, just getting a fastdebug build to go from start to
finish would probably be sufficient.

Actually, just having fastdebug Hotspot is really sufficient for what I want
to play around with, but I figure while I'm here I'll try to help debug the
Windows build process if I can. :-)

Let me start over and do a fresh build, capture the results (is there a good
way to capture the complete build output?), and send them to you. What
"make" command should I use? "make all DEV=1"? Something else?
