Is the use of HEADLESS in gcc.make (linux and bsd) an archaeological remnant and should be removed? (No source in the hotspot repo looks a the HEADLESS define.)

I agree this seems superfluous. There's no use of the HEADLESS define in the Hotspot sources.

Is there any reason to not build a headless version of awt? (ie modify BUILDHEADLESS to not be defined.) It seeems like headless is not currently built on bsd/macosx/windows, but it is built on solaris and linux?

I'm not sure what you are asking. BUILD_HEADLESS is a JDK build flag. As you say it is set true in the linux and solaris Def-.gmk files, and AFAICS it is only used in one place in make/sun/headless/Makefile

Note: BUILD_HEADLESS_ONLY is an unrelated option that was added to support special SE Embedded builds on platforms with no X11 includes or libraries available at all.
