GNU Bayonne and Common C++ do use a carefully constructed set of C++ features.  We have deployed complete Bayonne systems on 486sx machines installed with Debian with as little as 12 megs of ram.  So, the question of does C++ itself nessisarly imply/require use of a "large" amount of memory is largely mute.  However, I will agree that on a large system a few megs of memory is not going to be that relevant, although I would hate to waste 4 megs.  The problem is that FILENAME_MAX may be larger on some systems than even 4k.  I think 64 bytes is too few, but I would not wish to use an unknown or overly large quantity either.

How many trunk objects would there be on a high port capacity system?  Let's assume 1,000 and let's assume that FILENAME_MAX is 4,096B:

  4,096B * 1,000 = 4M

instead of

  64B * 1,000 = 62KB

So, for a system that is running 1,000 trunks it uses almost 4M of additional memory.  What kind of memory would you need anyway to run a 1,000 trunk system?  I don't think it would be doable on small hardware.  After all, we are already running C++ code here and if we were very concerned about memory usage I would've thought C would've been the language of choice.

But I'm not going to be stubborn.  If we are not doing FILENAME_MAX then what can we use so that my 100-150 character long pathname can work?

Perhaps apppath should be made larger; however, an instance is in every trunk object, and on high port capacity systems, which may also have very large values for FILENAME_MAX, this could prove very wastefull.
