Hi Alex,
Thanks for the testing. I'm not clear on what system you are building on.
It looks like Linux of some variant.
With the suggested modifications could you please provide full modified
files, as embedding lots of modifications into a single email, copying and
pasting modifications simply isn't a reliable means for me to attempt fixes.
Cheers,
Robert.
