Yes!!  This patch fixes the problem.  I finally have my code working
under gcj!

FYI, my code is a simulation based tool, and compiling with gcj gives a
significant speedup over using a jit:

                                  10,000 iterations   100,000 iterations
                                  -----------------   ------------------
Blackdown java 1.2.2 RC3 (w jit): 15 seconds          143 Seconds
gcj:                               9 seconds          90 Seconds 

Results agree to 15 digits.
