unable to build JLabel

[Pete Brunet]

After editing JLabel.java, deleting my build directory, and starting a
full build I am getting

make[5]: Entering directory `/cygdrive/c/OpenJDK/jdk8/jdk/make/javax/swing'
<snip - six sets of mkdir, rm, cp>
make[5]: *** No rule to make target `javax/swing/JLabel', needed by
`C:/OpenJDK/jdk8/build/windows-i586/../windows-i586-fastdebug/tmp/com/javax.swing/.classes.list'. 
Stop.

My build process was:
