Wait a minute: are you running ./configure directly in gcc source
directory when you are "doing it normally"?  No, you should make an
empty directory and run /path/to/gcc-x.y.z/configure.

If you've already done it correctly but the building system still
invokes "./configure" directly in libjava (or another subdirectory)
instead of running "/path/to/gcc-x.y.z/libjava/configure", something is
wrong in the building system.  Then we can't know why because we don't
know what you've done to GCC code.

Something you need to be aware of: if you are really doing a serious
project adding Java back to GCC, it's better to follow the FLOSS way and
publish the code somewhere.  Then it's easier to collaborate with
others.  The other people interested in Java and also experienced in
hacking GCC (forgive me if it's insulting, but it seems you are not so
familiar with GCC code to finish all the job yourself) can better help
you (I know almost nothing about Java, only able to write "Hello
world").  OTOH if you are just playing, I'll not reply anymore because
this list is for "help for building and using GCC", not "playing with
GCC".
