As a work-around, does "make demos-only" work OK?

It seems that on your Windows 8.1 machine the Java code is rebuilt as 
well, on top of the native code. I can't say for certain what causes this.

Once again, as a work-around, try "make java.desktop-libs" or "make 
java.desktop-libs-only", to only recomplie the native parts of java.desktop.

If you edit nothing, and run "make java.desktop" again on the win8.1 
machine, do you get a rebuild of the java code again? (i.e. Do you see 
the line "Compiling 2525 files for java.desktop"?)

Could you possibly have time skew issues? If the source code is 
timestamped in the future, then no rebuilds will ever make the resulting 
file look newer.
