Oh, this is Cygwin.  Ick.  gcj support for Cygwin is very iffy.  Last
time I tried you had to --enable-libjava to get it to build libjava as
it was disabled by default.  And even then it will only build a static
libjava which is not very useful.  Also the default SJLJ EH makes
performance nearly intolerable, so you'll probably want to switch to
Dwarf-2 EH.  I'm not sure if all the required patches for DW2 EH to 
function correctly on MinGW/Cygwin are in the FSF tree or not.  (Along
with the other problems with DW2 EH on Win32...)

If you google a little I think you can find hacks for building a MinGW
shared libjava which you might be able to adapt, but I don't know.  I
wouldn't expect much.
