Right, that could be a workaround for that one function, but isn't the whole lot of the long double functions missing?
John,
I'm sorry for the long long silence about this issue.
I have to admit I've sort of given up with making Boost libraries compilable with Comeau C/C++ back again. This is due to time constraints as well as the fact that it seems I'm "alone", meaning nobody seems to be using Boost with Comeau any more so there seems to be no such need to keep supporting Comeau.
So, I've suspended my efforts for a while and going to take them up as soon as time permits.
Thank you for your help and apologies for shutting the thread up.
No problem, I quite understand. If you get more time to investigate later then please do reopen this. Regards, John.
