Because the default build instructions don't work in this scenario, and
if all the effort to impliment a clone-config-make model was intended to 
encourage more users to attempt a local build (in order to try their hand
at a fixing a bug themselves or something) it makes sense to me to try
to maintain a scenario where OpenJDK can build to completion across a wide
variety of toolchains.

I don't agree. Someone should not have to be familiar with gcc options in
order to fix a typo, or change some Java code. And besides, we have a 
clear
and simple four-step build process (clone, get source, configure, make).
Why would we want people to have to fail their build and experiment with 
different options, when we can fix the problem right here and now.

In general, yes. In this one compile it's breaking the build.

David suggested disabling this warning. The simplest way I see to do this 
is to change Awt2dLibraries.gmk.

The code is here:

$(eval $(call SetupNativeCompilation,BUILD_LIBJAVAJPEG, \
    LIBRARY := javajpeg, \
    OUTPUT_DIR := $(INSTALL_LIBRARIES_HERE), \
    SRC := $(LIBJAVAJPEG_SRC), \
    INCLUDE_FILES := $(BUILD_LIBJAVAJPEG_INCLUDE_FILES), \
    OPTIMIZATION := HIGHEST, \

Switching the OPTIMIZATION to LOW will solve this at a stroke.
