The error messages generated when basic_filebuf is used with invalid
template parameters (wrong traits_type::off_type or traits_type::pos_type)
are not very good. The messages point to locations in fstream.tcc which
provide no info about what is wrong.

Let's mark this as an enhancement request.

Template error messages are something that C++X0 will address in core.
Once this solution is nailed down, we'll work on implementing it in the library.

The first test compiles now (it's implementation-defined whether it works or
not).

The other two fail a static assertion:

            Bug ID: 61117
           Summary: Manual uses term open source but should say free
                    software
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal

          Assignee: unassigned at gcc dot gnu.org
          Reporter: jgay at gnu dot org

In the manual for libstdc++, FAQ has the following entry:

http://gcc.gnu.org/onlinedocs/libstdc++/faq.html#faq.license.what_restrictions

2.4. I see. So, what restrictions are there on programs that use the library?

None. We encourage such programs to be released as open source, but we won't
punish you or sue you if you choose otherwise.



In the above, the term "open source" should be replaced with "free software."
