Error when building 0.99 on OSX (java_io_VMConsole.c: error: 'IUCLC' undeclared)

Hi,

I am trying to build classpath 0.99 (from 
ftp://ftp.gnu.org/gnu/classpath/classpath-0.99.tar.gz) on MacOS X 10.7. 
I am getting this error message:

    libtool: compile:  gcc -DHAVE_CONFIG_H -I. -I../../../include

    make[2]: *** [all-recursive] Error 1

Can anyone give a hint? Thanks very much.
