Apologies that once again I've taken months getting back onto this. I 
checked the code but there was still a problem, however I think that 
there's a possibility that I somehow screwed up getting the most 
up-to-date version (I don't claim great experience with SVN etc.). I 
took a bit of a look at the generated code using -al but I really need 
to get getting 2.4.0 onto the various development machines and re-test.

One question if I may: am I correct in believing that I need to generate 
the compiler with EXTDEBUG before -an works? Are there any undesirable 
side effects to doing this?
