Has anyone seen this build error before?

I tired to built libgcj from the CVS but got the following error:
gcj -B/home/mdejong/java/build_libgcj/i686-pc-linux-gnu/libjava/ -C -g 
-classpath 
/home/mdejong/java/build_libgcj/i686-pc-linux-gnu/libjava:/abomination/imagine/mdejong/java/libgcj/libjava -d /home/mdejong/java/build_libgcj/i686-pc-linux-gnu/libjava java/util/Date.java
java/util/Calendar.java:0: bad value constant type 8, index 91
make[1]: *** [libgcj.zip] Error 1
make[1]: Leaving directory 
`/abomination/imagine/mdejong/java/build_libgcj/i686-pc-linux-gnu/libjava'
make: *** [all-target-libjava] Error 2
Both the compiler and libgcj are from yesterday's CVS. I am
trying to build on a Linux box, it worked on this same box
before.
Any ideas?
