Hey Robert,

I'm going to look at this problem ronight, if it's possible to sneak this
into my lunch-break I'll try it out on my GCC 4.x on the Mac. I don't think
I have a GCC 3.x to hand. If I find it's ok on GCC 4.x I will endeavour to
get GCC 3.x installed somewhere.

I apologise for the disruption caused by this issue.

I will attend to the matter as quickly as possible.

Best Wishes,

Neil Groves
