Thanks - though it didn't seem to find anything for me, I'm afraid.
However I have now managed to get an apparently working compiler by
using the snapshot of 3.4 from 7th January. I'm quite satisfied with
this; however, I am a bit curious as to what might have happened in the
meantime (or what I've done to my system to cause this). One difference I
have noticed is that the snapshot from the 7th January did not create a
new wchar.h file (which I mentioned in my previous post). Perhaps I shall
try playing with the latest compiler source and see what I can find.
