The compiler gets a SIGSEGV attempting to build a .jar file.
It doesn't matter if the .jar is compressed or not.

 Unfortunatly this is still not working for compressed .jar files. With
 the current tree, I get:
 
 $ gcj --shared gnu-regexp-1.0.8.jar -o gnu-regexp.so
 gnu-regexp-1.0.8.jar:0: Not a valid Java .class file.
 
 (If I rebuild the .jar without compression, it works fine.)
