[kaffe] JVMPI status?

[Jon Nall]

tim,
thanks for the reply. i'm attaching the diff to this mail. the only bit 
i'm not sure about are the changes in jvmpi_kaffe.c. it looks like 
someone changed the definition of java_lang_String structs. the other 
diffs are just typos.

also, JVMPI functionality still seems broken, even with this patch. i 
get the stack trace attached below. i don't have time to look at it now. 
i might get to it this week, though.

nall.
