Ok.  I did a little more on this.  
 * Switched from gcc 3.0 branch to trunk, and  _Jv_Sjlj_Throw error "went
away"
 * Axed all reference to JNI_OnLoad from FirstThread, so that error went.  

Now when linking jv-convert.exe I get

./.libs/libgcj.a(natClass.o)(.text$_ZN4java4lang5ClassC1Ev+0x0): multiple
definition of `java::lang::Class::Class()'
./.libs/libgcj.a(Class.o)(.text+0x3a0): first defined here
collect2: ld returned 1 exit status
make[2]: *** [jv-convert] Error 1
 
Any ideas?
