Can you give specific examples? I'm unclear on the details.

In general, yes, it would be nice to abstract out as much detail as 
possible, and to have tests that are as portable as possible. 

However, as you've noticed, for filebufs in particular, details differ 
per host. (see the _M_buf_size_pref, to be precise.) Some effort has been 
expended to make sure the filebuf tests work on both solaris, linux, and 
cross compilers... 

I would be interested in suggestions to make things more portable.
