<AWT Dev> Fastest means to rebuild awt_Component.cpp

Kelly, I successfully built just awt.dll - well almost.  That alone
doesn't copy awt.dll/map/pdb over to the j2sdk image.  And it doesn't
build rt.jar. 

What do I have to do to get rt.jar built and j2sdk-image populated with
awt.dll and rt.jar?  Looking at a log from a full build it appears I
have to run the make in the launchers directory but that failed.  First
it builds appletviewer.res and its main.obj and then I see:

make[1]: *** No rule to make target
`c:/OPF6CE~1/jdk7/build/WINDOW~2/tmp/java/jli/obj/jli.lcf', needed by
make[1]: Leaving directory
make: *** [build] Error 2

By the way, to get awt.dll built (after doing a full build) this is what
worked for me, i.e. I had to set two more variables.  (I discovered make
-p and that was very helpful.)

cd \
set ALT_OUTPUTDIR=c:/OPF6CE~1/jdk7/build/WINDOW~2
rem same as c:\OpenJDK-b96m\jdk7\build\windows-i586-fastdebug
set ALT_JDK_IMPORT_PATH=c:/OPF6CE~1/jdk7/build/WINDOW~2/J2SDK-~1
rem same as c:\OpenJDK-b96m\jdk7\build\windows-i586-fastdebug\j2sdk-image
OpenJDKBuild-b96m.bat <-- sets the variables that are needed for a full
eval `bin/vsvars.sh -v10` <-- at cygwin prmopt
cd /cygdrive/c/OpenJDK-b96m/jdk7/jdk/make/sun/awt
make 2>&1 | tee build.log

Thanks, Pete
