idlc - compiling -Wall

[Ken Foskey <waratah@zip.com.au>]

Benhard told me about some features in the idlc code.   I have worked 
though the code to make it compile -Wall.  This has exposed some 
features with the error handling but would not nessecarily explain any 
crash in it.  Some printing as string of structures not the text within. 
 Anyway there are a couple of places that unicode strings are printed 
with fprintf from a registry variable.   Is there a way to print unicode 
directly with a % something or do I look for a conversion function?

Thanks
