There is a custom GCJ for mingw32.
However, it doesn't support all java features (generics<generic>, for example):)
So, I am hoping to use the official Gnu project GCJ, and not the custom mingw32 one.
 
However, I can't ./configure; from the unzipped, un tarred
gcc-java-4.6.0.tar.bz2
file which seems to be the place to start with.
 
-Does this compiler allow one to compile to binary machine code exectables,
and not just java .class files?
-What are the commands to generate Linux/Mac OSX/Windows XP or 7/
native code?
-How do I successfully build and execute the compiler to begin with?
