So I have to specify the above to get java to build?  Well not on ARM
GNU/Linux, it decided to try to build the java stuff.  Is there an
exclusive configure option to tell it not to build java?  Something like
--disable-language=java,...


I also needed the following patch, not certain if this is completely
correct:

[build@feynman gcc]$ cvs diff -up boehm-gc/gcconfig.h

Then it failed with the following:
