compile error

hi, i'm getting a compile error on Solaris 9 with the following config
options:

% ./configure
--with-includes=/opt/local/include:/usr/include:/opt/sfw/include
--with-libraries=/opt/local/lib/:/usr/lib:/opt/sfw/lib --with-java

i previously had successfully compiled and installed version 7.3.2.
please let me know if i can provide other information to help sort this
out.

regards,
patrick barabe
