make; for GCJ doesn't want to finish!

I have download the files again,

gcc-core-4.6.2.tar
gcc-java-4.6.2.tar

I find that when I paste the java files into the core files,

that the java files have a duplicate copy of one gcc directory.

I click to replace (merge) the java gcc version with the core version.

Aside from this, I am still getting the problem of

make install;

I do have windows notifying me that "GPLed" doesn't want to work, or is blocked.
